Measurements

David Ballo, Agilent Technologies

While in the past it was often sufficient to only characterise the magnitude response of these components, today’s engineers must also know the phase and group delay response as well.

Having both magnitude and phase information for all of the components of a system means designers can simulate and optimise the overall system performance.

Traditionally, vector network analysers (VNA) have been the tool of choice to characterise the magnitude and phase performance of a mixer or frequency converter. They offer two or four test ports, one or two internal RF sources, fast sweeps (compared with using stand-alone signal sources and a spectrum analyser or power meter) and provide complex data of both reflection (eg, input and output match) and transmission responses.

VNAs can offset their source and receiver frequencies, a necessary capability to test frequency-translating devices.

Typically when using a VNA, two additional mixers are needed to characterise the device under test (DUT). The first mixer provides a signal to the VNA’s reference receiver at the same frequency as the output of the DUT.

This signal provides a phase reference for ratioed measurements of phase and group delay versus frequency (Figure 1).

In older VNAs, the reference mixer was also used to phase-lock the internal source to the correct offset frequency. In contrast, modern VNAs use fully synthesised RF sources that do not require a reference mixer to generate the proper stimulus signal.

Calibrating a VNA for these measurements requires both a power reference and phase reference, as well as standard S-parameter cali-bration standards like an ECal module or a mechanical calibration kit. Power calibration is done using a power sensor.

Instruments like the PNA family of network analysers calibrate all the receivers for the test ports based on a single source-power calibration at port one and the standard S-parameter error terms

between the ports. Calibrating the phase response of the receivers is most commonly done with a second mixer.

This calibration mixer is used as a charac-terised through standard, meaning its vector reflection and transmission responses are known. One way to do this is to perform three reflection measurements at the input of a reciprocal calibration mixer with an appropriate output intermediate-frequency (IF) filter, while presenting three different impedances to the output of the mixer/filter pair.

These impedances can come from open, short and load standards or from an ECal module. From this, the input match, output match and two-way transmission response can be calculated. Using a reciprocal mixer, the one-way transmission response can be determined by dividing the two-way response in half.

While this method is relatively straight-forward and has been commonly employed, in practice it is often difficult to find the proper reference and calibration mixers and the appropriate IF filter, especially when a broad range of DUTs must be measured and especially above 26.5 GHz.

Providing a local-oscillator signal to the reference and calibration mixers can also be cumbersome, particularly when using older VNAs with no built-in second source.

Simplifying frequency converter testing

Frequency-translating components - devices like mixers or frequency converters that shift an input signal from one frequency band to another - are key elements in most RF and microwave systems. They are found at the core of satellite receivers and transponders, radar systems and telecommunication networks


Measurements

A simpler alternative would speed up measurement set-up and calibration, making design and test engineers more productive.

One solution to this dilemma is the new SMC+phase method, which was developed for the Agilent PNA and PNA-X series of microwave network analysers. This method eliminates the need for both a reference and calibration mixer when testing the phase or group delay of frequency-translating devices.

Instead of relying on ratios of test and reference signals at the same frequency (which requires a reference mixer), it ratios single-receiver phase measurements done at different frequencies (those corresponding to the DUT’s input and output).

This technique relies on the inherent phase coherency of the fractional-N-based synthesis architecture used in the PNA’s sources. Relative phase coherency is main-tained across a frequency sweep by digitally incrementing the phase accumulators em-bedded in the fractional-N hardware, and by employing synchronous IF detection and digital-signal processing.

At band-crossings, where changing synthesiser-divide numbers cause discrete phase jumps, the phase is mathematically stitched together to maintain phase coher-ency across the sweep.

Sweep-to-sweep starting-phase variation is removed by normalising one point in the phase sweep to zero, which allows sweep averaging to be employed as an effective noise-reduction technique.

In conjunction with single-receiver phase measurements that eliminate the reference mixer, a new phase calibration method has been developed that eliminates the need for a characterised through mixer. Instead of using a mixer to determine the phase-versus-frequency response of the PNA’s receivers, a harmonic comb generator is used to create

a broadband set of signals with 10 MHz spacing, extending all the way to 67 GHz.

The comb generator, which is calibrated by electro-optical methods developed at the National Institute of Standards and Technology, is identical to the phase references used with Agilent’s nonlinear vector network analyser (NVNA).

Once phase calibration is done, accurate measurement of phase deviation and absolute-group-delay can be performed. As with previous SMC measurements, a power sensor is used to accurately calibrate the magnitude-versus-frequency response of the receivers (Figure 2).

SMC+phase measurements can easily be done on devices with embedded LOs that are not locked to the system 10 MHz reference. The measurements use previously developed search algorithms that tune the PNA receivers to the actual output of the DUT, instead of relying on nominal LO frequencies (Figure 3).

The tracking is done sweep by sweep to keep up with LO drift. Unlike the modulated-carrier envelope approach to testing DUTs with embedded LOs, the PNA’s method is simple and does not require two RF sources and a signal combiner.

In addition, it enables phase-versus-drive meas-urements to characterise phase change versus RF input-power levels, something that cannot be done with the envelope method.

With the PNA and PNA-X family of microwave network analysers, mixer and converter test has never been easier. The new SMC+phase method uses single-receiver phase measurements to eliminate the need for reference mixers.

Connecting to the DUT is as simple as connecting input and output cables and, if needed, connecting a third cable to the instru-ment’s built-in second source for use as an LO signal. A new phase calibration method uses a broadband harmonic comb generator as a phase standard to eliminate the need for calibration mixers and their associated IF filters.

The method promises to revolutionise mixer and converter test by providing a simple set-up with fast, accurate results based on easy-to-use broadband calibration standards.

Simple and fast characterisation of mixers and frequency convert-ers makes design and test engineers more productive, helping them decrease time to market and lower the cost of test.

A simpler alternative would speed

up measurement set-up and

calibration, making design and

test engineers more productive.

Figure 1. The traditional approach to testing mixers and frequency con-verters requires a reference mixer to provide a signal at the same frequency as that present at the DUT output, for ratioed phase measurements between the R1 and B receivers.

Figure 2. The SMC+phase set-up is simple, since reference and calibration mixers are not required. Test system calibration is achieved using a power sensor (left), a broadband comb gen-erator (middle) and an ECal module (right) or a mechanical calibration kit.

Figure 3. When measuring devices with embedded LOs, the PNA uses a coarse frequency sweep (top) to determine the nominal LO offset. A phase-versus-time sweep (bottom) is used to finetune the estimate of LO offset.


Surge generatorThe EM Test surge generator type VSS 500N10.3 is specifi-cally designed to generate high voltage transients as required by IEC/EN 61730-2 for safety testing photovoltaic panels.

The generator features the full range of capacities that load photovoltaic panels may represent, offering 7 x different load ranges. Each range is based on a separate pulse-forming network to comply with the tolerances given in the standard.

As usual for all EM TEST equip-ment, the device offers manual operation via a front-panel menu with function keys enabling the user to program test routines quickly and accurately.

The cursor allows fast control of all test parameters of the programmed routine, so testing is simplified.

M2M wirelessThe 802.11 b/g Wi-Fi access point to provide M2M equipment with wireless networking capabilities has been launched.

This industrial-grade wireless access point is the first fruit of B&B’s October 2011 acquisition of Quatech, whose Airborne wire-less networking devices feature Wi-Fi connectivity technology to network-enable industrial M2M devices.

The latest product is in two forms: an embeddable module (APMG-Q551) allows original equipment manufacturers to Wi-Fi-enable their own products so they can either serve as self-sufficient M2M wireless communications hubs or tie into existing wireless networks; an external ethernet access point (APXG-Q5420) provides the same functionality in a ruggedised stand-alone box and adds serial device server capability as well.

The technology allows the access-point-equipped device, whether it’s the external APXG or an OEM’s device fitted with the APMG, to become the centre of its own self-sufficient Wi-Fi network.

The external APXG is equipped with a typical ethernet port, plus two serial ports not typically found on wireless access points.

With the ability to connect and route between any of its ports, the APXG can serve as an access point (handling up to eight simultaneous client connections) or as a bridge (tying Wi-Fi de-vices into ethernet networks), while simultaneously serving as a serial device server (bridging serial devices into either wired or wireless LANs.)

In-flight antennaCable-based antennas or leaky feeders have been introduced to improve signal propagation without increasing the amount of hardware required on an aircraft.

Suitable for both wide-body and single-aisle passenger air-craft, the antennas provide reliable access to different wireless protocols so passengers can connect to in-flight entertainment, internet servers and email accounts.

The cable-based antennas are installed along the length of the cabin ceiling, and with signal propagation occurring every metre along its length, passengers have reliable access regardless of their location. Signals are transmitted via a signal network computer and outside antenna to satellites that connect to the worldwide network.

Unlike typical broadband technology that requires separate hardware for each type of wireless access, this antenna requires only one set of hardware to service the entire aircraft.

This antenna sends and receives signals in frequencies rang-ing from 400 MHz to 6 GHz, which makes it compatible with numerous communication standards, including Bluetooth, DECT, DECT2, Global Star, GSM, Iridium Sat, MMS, PDC, TETRA, UMTS, WLAN 802.11 a/b/g, and WiMAX.

Lightning monitoringThe LM-S lightning monitoring system provides online informa-tion about lightning strikes in a plant.

The system identifies and analyses all the important param-eters of lightning surge currents based on the Faraday effect. A light signal is used as the measuring medium. The way in which this light signal is influenced provides information about the type and magnitude of the lightning strike.

This information can be used to optimally plan monitoring and maintenance activities. This is especially advantageous for plants and systems in exposed locations such as wind turbines.

The system comprises an evaluation unit with up to three sensors. The sensors are mounted on the discharge conduc-tors that conduct the lightning current. They are connected by fibre-optic cables to the evaluation unit, which communicates with existing supervisory control or management systems via an ethernet interface. The integrated web interface allows access to the most important data of all of the monitored systems via the system’s own network.

Power suppliesContact-cooled AC power supplies from 50 to 750 W will not fail even when things become particularly heated. This is because sealed modules with a cooling plate do not require any air as long as they are installed on the appropriate application surfaces.

Cosel power modules are encapsulated power supplies mounted on printed circuit boards that dissipate the heat they generate exclusively through an aluminium base plate and do not require any additional fans or special flue effects.

These heat-conductive contact surfaces can reach tempera-tures of up to 100°C before an integral overtemperature trip puts on the brake. The power modules are designed for permanent operation under full load in 24/7 mode.

The TU series of single modules requires an external EMI filter to attenuate line-based faults. The supply range begins with the 50 W module on a ¼-brick space of 37 x 59 mm with a height of 12.7 mm. The range extends from 100 to 300 or 500 W in a full-brick format.

The TUNS basic versions have safety shut-offs as standard for overvoltage, overcurrent and overtemperature as well as a settings range for output voltage and additional remote sensor connections to compensate for voltage drops in the output cables.

The most powerful version with a permanent output of 500 W also has an additional peak power potential.

The current range of DPG/DHS modules has been extended with a plug-and-play-enabled option for the SNDPG module and the SNDHS series. The power modules can be supplied on complete assemblies in the form of a printed circuit board with a filter, fuse and plug or screw connectors on an aluminium base plate.

The user has to only complete the mechanical assembly us-ing the 3 mm thick base plate. This means that robust CE- or UL-compliant AC power supplies with an output of up to 750 W can be produced in minutes. Output modules with 50, 100 or 250 W are supplied from an AC front-end module to correct harmonics with floating output voltages between 3.3 and 48.

Power MOSFETsVishay has released the first devices in its next-generation D series of high-voltage power MOSFETs.

The 400, 500 and 600 V n-channel devices combine low specific on-resistance with ultralow gate charge and currents from 3 to 36 A in a wide range of packages.

The devices’ stripe design - with a smaller die size and terminations - lowers the total gate charge by 50% while increasing switching speed and reducing on-resistance and input capacitance.

The devices feature on-resistance down to 0.17, 0.13 and 0.34 Ω.

The ultralow on-resistance values translate into low conduc-tion and switching losses to save energy in high-power, high-performance switchmode applications. These include server and telecom power systems, welding, plasma cutting, battery chargers, ballast light, high-intensity discharge (HID) lighting, semiconductor capital equipment and induction heating.

Keeping track of data centre functions

The system's knowledge -

or intelligence - is not in the

transponder itself but in the

databases.

RF devices

F e w d a t a c e n t r e s today keep automatic inven tor ies o f the i r servers and infrastructure components. As a result, many IT administrators are unaware of the current use levels of their server racks and IT infrastructure.

One solution is the use of RFID technol-ogy, which offers a way of improving the security and efficiency of data centres.

Which rack houses the server for my ERP systems? Which server enclosures of-fer sufficient cooling capacity and power supply for installation of another blade? How much power does a particular device in the enclosure consume at full use? And what are its cooling requirements?

Many administrators have difficulty answering questions like these quickly and accurately, even though they are faced with them daily.

This is due to both the number of server racks and the complexity of the hardware components. Up-to-date and reliable information on the device structure per rack is often hidden away somewhere in Excel sheets or would only be available through a constant and time-consuming process of manual inventory monitoring.

What’s more, manual data entry only provides a snapshot of the data centre inventory. RFID has been used for years to optimise processes in the logistics industry and now provides a means of automating inventory procedures in data centres. Radiofrequency identification enables contact-free detection of objects or people via radio and every system in-frastructure includes a passive transponder, a transceiver unit and an IT system that works in the background.

The transponder - a microchip with antenna coil - is integrated into a carrier object and can be read and written using

radio. This tag contains a code to which information (stored in a database) can be assigned and so gives every object a unique identity.

The tag sends information to a reader unit, which forwards the code to a database. Here, a software program decrypts the code and links it to the stored information on the properties of the carrier object.

The system’s knowledge - or intelligence - is not in the transponder itself but in the databases.

Dynamic rack control (DRC) from Rittal is an RFID infra-structure developed specifically for use in data centres.

It uses the radio technology directly in-side the rack to log component population of the 482.6 mm (19″) level contactlessly and in real time. IT components, eg serv-ers or switches, equipped with RFID tags, send information continuously to an aerial strip installed in the server enclosures.

As the rack is fitted with one sensor per mounting hole, separate data can be accessed for every height unit (U), and so the precise location of every device is recorded immediately and without any contact when it is installed.

The tags also provide basic information on the installed device, such as the manufacturer, type of component, date of installation and software. The tags are permanently assigned to the devices.

If the position of hardware changes, eg, it is moved to a new rack, this information is registered and reported automatically. As a result, administrators know where every server is installed.

When populating racks with components, administrators all too often rely on rules of thumb instead of taking into account factors such as efficient power supply and cooling. Incorrect identification of component positions and insufficient docu-mentation can have serious consequences if the infrastructure is overloaded through the installation of an additional device.

In the worst case, this can result in complete server failure

Switching regulatorMornsun’s second-generation R2 series of its K78 series of regulators has improved ripple, noise and EMI.

The K78xx-500R2 series is also suit-able for problems with negative voltage applications. When used as a negative voltage device, the series still has a high level of efficiency and low ripple.

The device can operate as either a positive or a negative output voltage regulator and is a drop-in, high-efficiency replacement for the LM78xx 3 pin series of regulators.

R2 series stands for lower power con-sumption and better EMC performance. The series meets EN55022 Class A for power and with the 4.75 to 32 VDC ul-trawide input range, its efficiency can still be up to 96%.

As a result, this means the device works well in the -40 to +85°C temperature range without a heat sink.

The devices also have short-circuit pro-tection, overload and thermal protection without any extra circuitry or components.

and downtimes in a company’s operations. Failure in the server room is particularly precarious for IT service provid-ers and collocation providers who have to fulfil service level agreements for their customers.

Inventory monitoring using RFID technology in data centres helps avoid such downtimes in the IT infrastructure.

Functions for identifying component positions, recording the device type and serial number, and sorting data records and meta data, such as the purchase data and maintenance intervals, are available at the touch of a button.

An automated inventory system with RFID also creates the basis for monitoring, eg, through integration into an infrastructure management software such as RiZone, which is optimised for the physical infrastructure of a data centre.

It also manages infrastructure compo-nents, such as power supplies in the server rack and cooling right down to rack level. Most of these components have networking capability today and can communicate their status via SNMP or BACnet.

If the RiZone management platform is connected to the Microsoft System Centre Operations Manager (SCOM) for example, the system displays all important alarms and relevant parameters for cooling, power supply and energy consumption on a single user interface.

This makes it possible to manage the entire data centre, ie, services and hardware, from one standardised interface. In ad-dition to improving energy efficiency and reliability, in case of failure this system also makes it possible to relocate applications faster and to find and exchange devices more quickly.

The ability to store key component data on passive RFID tags makes it possible to identify free capacities at the 19″ level of the racks and obtain information on both the installed electric output and - using temperature sensors - the climatic conditions.

In this way, a current overview of the components installed in the racks, separated according to device category, power consumption or cooling demand, is available at any time.

The rack configurations can be displayed in the infrastructure management software. They can be called up as lists or imported/exported using the XML file format. These data records can then be further processed in external databases and play a key role in simplifying the day-to-day optimisation of data centre operations quite considerably.

This way, every rack can be populated with IT components as efficiently as pos-sible in terms of space, cooling output and power supply. Every extra height unit gained in data centre rooms, which tend to suffer from a chronic lack of space, means improved performance.

Transit racksErack is a lightweight, 19″ ruggedised aluminium transit rack for electronic equipment, specifically designed for commercial and military applications when protection against physical, cl imatic and electromagnetic hazards are required, and where weight, strength and port-ability are critical issues.

The rack's external container has a rim that eliminates the edge extrusion and makes the case stronger, lighter and more resistant to ingress by water and dust.

The internal chassis frame is supported by special mounts which protect against shock and the unit is up to 30% lighter than other rack cases in its class.

It has front and rear access via precision interchangeable lids. Each lid is secured to the rack body by front-mounted, quarter-turn latches (allowing front and rear access when stacked).

Positive location between lids and body is achieved by male/female extrusions which incorporate a silicon seal giving all-weather protection to IP66.

The chassis is constructed from alochromed aluminium al-loy, punched with ‘burst holes’ giving enhanced lightness and rigidity. The chassis is mounted on eight elastomeric mounts, fixed to the outer casing by robust anchor plates, which are focused towards the centre of mass of the case, ensuring the electronic equipment is protected against vibration and impact.

The suspended inner chassis can move up to 50 mm indepen-dently of the outer container and in any direction. An earthing/grounding strap is fitted to maintain conductivity between the equipment and the outer container.

Agilent Technologies/Trio SmartCal - stand C35Agilent Technologies continues to expand the capability of its X-series of oscilloscopes by offering 1 GHz models for the growing need for higher-bandwidth bench scopes.

Doubling the available bandwidth addresses the top user-requested enhancement for this family. The 2000 and 3000 X-series have features such as WaveGen, which integrates fixed-function and arbitrary waveform stimulus with oscilloscope response measurements.

The company claims to be the first major test-instrument vendor to integrate a function generator with an oscilloscope. This integration is useful for users who want to simplify stimulus-response testing, R&D engineers who need to simulate missing signals and educators who want a simple tool for teaching students about instrument operation.

With the upgraded AWG software, users can capture waveforms and instantly convert them to stimulus files - and even edit the captured waveforms within the oscilloscope. It’s easy to stress a design by adding noise, changing frequency and amplitude, and adding glitches.

In addition, both the 2000 and 3000 X-series now offer the option to add a 3-digit voltmeter and 5-digit counter that operate through the same probes as the oscilloscope channels.

These measurements are decoupled from the oscilloscope triggering system, allow-ing engineers to make DVM and triggered oscilloscope measurements with the same connection.

The series has update rates of 1,000,000 waveforms/s and options include a 16-channel MSO, an integrated function generator and hardware-accelerated serial protocol decode.

The resin carries no health warnings, thus providing a much safer environment for opera-tors. In addition, it is a low hardness material and allows easy removal of cured material for rework processes due to its ‘digoutable’ properties and translucent amber colour.

With high flexibility at temperature extremes of -70 to +100°C and good electrical proper-ties, the resin provides a solution for low-hazard potting and encapsulation applications.

The SC range of silicone products on show features the SC3001 that is an optically clear and flexible two-part encapsulation compound, developed specifically for the LED industry where optical clarity is essential.

It features low viscosity and good electrical properties and flexibility. It also has good re-sistance to water and a wide range of chemicals. Resins in the 2000 series include SC2001 - a general potting and encapsulating compound, SC2001FD - a fast cure compound and SC2003 - a thixotropic compound.

Being demonstrated will be the Graco PR70 dispensing machine. This positive displace-ment air-driven machine will show how two-part materials, polyurethane, epoxies or silicones can be dispensed from a small shot size of 2 cc and upwards at a ratio accuracy of ±1%.

Tank size options are available with stainless steel in 7.5, 30 and 60 L or the polyethylene 8 L.

Altronic Distributors - stand C27Altronic Distributors has released the N 2104 Manson heavy-duty, 12 V battery isolator, designed for use in dual battery systems, eg, a main battery and an auxiliary battery.

The auxiliary can be connected to load, such as a camper fridge, while the main battery is isolated and does not draw cur-rent.This allows the user to start a vehicle using the main battery if the auxiliary battery is flattened by the load.

The device automatically connects the auxiliary battery for charging once the main battery reaches the selected voltage and disconnects it from charging when the main battery falls below a selected cut-off voltage.

The isolator may also be used with a single battery operating as a low-voltage cut-out to prevent overdischarge.

The device has a solid state design, has no moving parts, suits most lead acid bat-teries and has a manual override option.

Bright blue lightOsram Opto Semiconductors’ Oslon signal LED is claimed to provide the brightest blue light, using a special thin-film chip. The Oslon Signal emits powerful bright blue light and can be operated at a high current to provide steady brightness.

A luminous flux of 52 lm at 350 mA and its wavelength of 472 nm means it complies with the US and EU standards for signalling, particularly for emergency vehicle lighting.

The package platform of the family, consisting of a ceramic sub-strate with built-in connecting contacts and a silicone lens, remains stable and resistant to ageing.

The device incorporates high-performance UX:3 chips, which can operate at high performance levels even at high currents. This is an important aspect, as blue signal light is often pulsed and therefore requires even greater luminous power at high currents.

The lens has a radiation angle of 80° and provides a symmetrical light output.

The relevant international standard is EN 60529, which defines ratings written as IPxx, where the first digit defines the protection against solid objects and the second the protection against water ingress.

The standard sets out the criteria.•Protection classes for protection against contact and solid bodies•Protection classes for water protectionA typical enclosure for general-purpose

use might be rated IP54; one for use in hostile environments at IP65; and for use in extreme applications, IP66 may be required.

An IP54 enclosure could be used as a handheld controller for shop floor equip-ment; an IP65 one for equipment outside; and for housing electronics in areas such as food production, where it will be regularly hosed down, IP66 will be needed.

In general, enclosure manufacturers will use two main techniques to achieve the designed protection level. Satisfactory IP54 sealing is readily achieved by using a tongue and groove construction to the joint between the body of the enclosure and a removable panel or lid.

No gaskets are used. The seal is achieved through the combination of a recess in the base section that mates to the correspond-ing mirror profile in the lid when the lid is screwed down.

To achieve higher levels of sealing, a gasket between the two mating halves will be required. Typically, gaskets will be one

of two types. Either a silicone gasket will be injected as a liquid into a groove in one of the mating surfaces as part of the manufacturing process; when it self-cures it is permanently affixed to the enclosure.

Alternatively, a separate, preformed moulded neoprene gasket is inserted between the two mating surfaces.

The separate gasket approach has a number of advantages: a metal enclosure can be painted if required without having to mask the gasket area; the gasket can be easily replaced if it is damaged and, again in a metal enclosure, a conductive gasket can be used to give both environmental and electrical screening.

To eliminate potential weak spots in the seal, it is standard practice to ensure that the fixings are positioned outside the sealed area so that the integrity of the seal is not compromised by screws passing through or inside it.

The majority of enclosure manufactur-ers will quote the IP rating of their prod-ucts as part of the specification, enabling the project engineer to select the most appropriate packaging for the intended application - to inadvertently end up with an ideal enclosure that also happens to be rated at IP67 for equipment that will only ever be used in the office environment could be somewhat over the top.

As always, the best advice is to talk to the specialist enclosure supplier as early in the design cycle as practical; timely advice on the selection of the enclosure frequently saves a lot of development time and money.

10,000 MW DC transformer saves power lossesABB developed and tested a 1100 kV ultra-high-voltage direct current converter transformer. It is claimed to break the record for the highest DC voltage levels ever and facilitates an increase in power that could be transmitted efficiently over longer distances.

The Xiangjiaba-Shanghai link, commissioned by ABB was said to be the world’s first commercial 800 kV UHVDC connection. It has a capacity of 6400 MW and covers a distance of just over 2000 km, making it the longest of its kind in operation.

The new transformer will make it possible to transmit more than 10,000 megawatts (MW) across distances up to 3000 km.

Higher voltage levels allow larger amounts of electricity to be transported across very long distances with minimal losses using HVDC technology. Converter transformers play a critical role in HVDC transmission serving as the vital interface between the DC link and the AC network.

Development of the 1100 kV transformer addressed several technology challenges such as the sheer size and scale, electrical insulation, including bushings, and thermal performance.

Supply and demand for LEDs even outDemand from LCD backlights will continue to dominate LED demand until 2013, when it will reach its peak, according to the NPD DisplaySearch Quarterly LED Supply/Demand Market Forecast Report.

Last year was challenging for LED makers. After taking off in 2010, the growth in demand from LCD TV backlights reversed course, due to a combination of slower growth in LED backlight LCD TV sales and slower growth in chips used per backlight, due to efficiency increases.

The demand for LEDs in LCD backlights did grow slightly, as use in tablet PCs and strong penetration growth in LCD monitors made up for the drop in demand from TV.

Growth was also modest in lighting, as the market penetration of LEDs only grew from 1.4% in 2010 to 1.9% in 2011.

At the same time, many new LED suppliers had entered the industry and were rapidly ramping up production. Measured in standard units of 500 x 500 micron chip size, supply grew by 41% in 2011, compared with only 10% growth in demand. This resulted in a significant over-supply throughout 2011.

Due to the growing popularity of new, low-cost direct LED backlight designs for LCD TVs, the demand for LEDs in backlights will continue to increase through 2013. While the number of LED packages per LCD backlight unit will peak in 2012, continued growth in penetration of LED backlights will lead to a slight increase in LED demand in 2013.

By 2014, lighting will become the dominant source of demand for LEDs as price reductions and efficacy improvements drive increased adoption.

The penetration of LEDs in lighting will reach 16.8% in 2015, according to the report that also found that spotlights and LED street lights will gain higher penetration in lighting due to government incentive programs, such as the 12th Five Year Plan in China and the LED subsidy policy in Taiwan, as well as continued growth in commercial applications.

LED bulbs and fluorescent tubes are growing in Japan due to government incentive programs and energy-saving consciousness, especially following the March 2011 earthquake.

Infrared emitterThe infrared Mini Midled is 0.9 mm high, but it produces a nar-

row and intense beam of infrared light that is said to provide the highest radiant intensity of its size class.

With a radiant intensity of 60 mW per steradian (mW/sr) at 100 mA it is suitable for proximity sen-sors and light barriers in devices where space is limited.

The radiant intensity (meas-ured in watts per steradian) indicates the optical power within a solid angle and, therefore, de-fines the intensity of the emitted beam of light.

The advantage of the device is its half-angle of 17°, producing a narrow light beam with a radiant intensity of 60 mW/sr at 100 mA. This is achieved by focusing the light with a metallised reflector integrated into the device.

Ethernet/IP adaptersThe Allen-Bradley FLEX I/O dual-port ethernet/IP adapters from Rockwell Automation help OEMs connect machines to their customers’ IT infrastructures using a single network. With the dual ports, users can also leverage the adapter to display diagnostics via a simple web browser, helping reduce troubleshooting and downtime.

The adapters support a device-level ring topology that provides network infrastructure and fast recovery time, while keeping im-plementation costs down. DLR infrastructures are connected at the end device versus the switch. With no need for unnecessary switches and cabling, users can reduce design time and simplify implementation.

The ring also adds a measure of redundancy that is very effec-tive when a connection fails - as a single network failure, such as

a cable break, will not lead to the failure of the other devices in the ring. A DLR network can recover in less than 3 ms for a 50-node system.

During this time, the connection between the programmable automation controller and the I/O device is not interrupted. The adapters also support the daisy-chain topology for applications that involve devices located long distances from CPU subsystems.

Exploration of design ideas is the foundation of any design workflow. It helps create compelling products with unique value propositions that separate them from the competition.

For engineers, idea exploration takes the form of prototyping and testing algorithm variations to evaluate their behavioural and functional effect on the final product design.

Such evaluation narrows the set of al-gorithm alternatives and helps identify the one that eventually make its way into the design of the entire system.

The speed with which an engineer can design and assess algorithm variations is critical to efficient optimisation of the de-sign. The high-level interpreted language of MATLAB is a choice for engineers to express their ideas during design exploration, because it lets them focus on algorithm behaviour instead of low-level programming details.

As product development evolves from algorithm exploration to system design, inte-gration and implementation on hardware, the design specifications are typically translated by hand into a language such as C or C++.

The C programming language has broad popularity and is widely accepted as the language of choice for many development phases including system design, applica-tion software development and embedded software implementation.

Often engineers translate MATLAB algo-rithms to C/C++ code to create stand-alone software prototypes, integrate MATLAB algorithms with other software written in C/C++ or deliver specifications to embedded

software engineers for implementation. Generating C automatically (and nearly instantly) from MATLAB speeds design exploration and product development iterations.

The pitfalls of manual translation stem from differences in the program-ming paradigms of MATLAB and C. MATLAB has a succinct syntax and native data types for the vector and matrix processing operations used in embedded signal processing and control algorithms. The equivalent C code requires multiple loops to process individual data samples, resulting in many lines of C code for a single line of MATLAB code.

Equally important, the polymorphic and dynamically typed be-haviour that makes MATLAB flexible and easy to use is not readily accessible in the more statically typed C language without detailed programming. These differences make manual translation a time-consuming and complex process.

Manual translation also results in multiple copies of the same al-gorithm written in different languages. The engineer must verify that these copies remain equivalent throughout multiple design iterations.

The cost of verifying and updating revisions to accommodate requirement changes quickly becomes prohibitive, often resulting in errors and a design that diverges from the original specification.

Automating translation of MATLAB code to C code overcomes most, not all, of the problems associated with manual translation. Automatic MATLAB-to-C code generation offers these advantages:

•Design engineers spend more time innovating and tuning high-level algorithms in MATLAB rather than writing and debugging low-level C code;

•The equivalence of MATLAB algorithms and generated C code is easily maintained during design iterations;

•C code is produced much faster and is free of the errors that are frequently introduced by hand coding.

The automatic translation workflow from MATLAB allows en-gineers to maintain ‘one truth’ - and elaborate it directly within MATLAB to incorporate implementation details such as specifying data types and sizes of input and output variables.

Design iterations become easier because engineers continue to use the interactive debugging and visualisation capabilities in MATLAB throughout the process.

The cost of producing and verifying handwritten C code can be eliminated for common design workflow uses such as prototyp-ing algorithms as stand-alone executables, integrating algorithms as re-usable libraries and accelerating parts of the algorithm’s execution in MATLAB.

Translating MATLAB code to C code (automatically or by hand) involves making decisions on multiple implementation details in the algorithm such as data type management, fixed-point maths support and static/dynamic memory allocation.

Choices made by engineers when working with these details help satisfy various implementation requirements and enable the engineers to manage trade-offs between reducing memory footprint and improving processor use or performance.

As an automatic MATLAB to C code generation tool, MATLAB Coder enables engineers to specify these requirements and make implementation decisions directly within MATLAB. This makes it easier to maintain one reference design and iterate on the evolving design in MATLAB.

The following sections of this article describe the recom-mended three-step workflow that enables engineers to specify the implementation details that are needed to convert their MATLAB algorithms into the desired C code and verify the resulting code against their original MATLAB specification. This workflow is illustrated in the figure below.

The first step in the code generation pro-cess is to prepare the MATLAB algorithms by introducing implementation details and ensuring the code is using the subset of the MATLAB language that is supported for code generation. This subset includes basic operators, numerical computations, standard programming constructs and hundreds of built-in functions.

Implementation details are required to prepare MATLAB code for code generation because MATLAB is polymorphic - the behaviour of its operators and functions adapts to the nature of the input argu-ments they are operating on.

A result that can be achieved with a few lines of MATLAB may require tens or hundreds of lines of C code. For example, a simple function that multiplies two inputs of any size and data type is a single line of MATLAB code. When coding this in C, the engineer must take into account the size and data types of the inputs as well as whether they are real or complex. This is illustrated in the figure below.

Polymorphism is one reason that MATLAB is a versatile and convenient language for exploring design ideas. When writing C code by hand or generating it with MATLAB Coder, however, engineers must explicitly specify the input sizes and data types for their algorithms. In MAT-LAB Coder, this can be done through the command line interface or the project UI as shown below.

For the same reason, certain local variables within the algorithm code in MATLAB have to be pre-allocated so the code generation engine knows the sizes and the data types of the variables to be used in the generated code.

Another key step in the preparation pro-cess is to check if the MATLAB algorithm code uses only those language features and constructs that support code generation. The product documentation lists all sup-ported functions and language features.

In the traditional workflow, verifying that the handwritten C/C++ code function-ally matches the original MATLAB algo-rithms is an important and challenging task.

Two common approaches are used to perform this functional verification:

•Maintain separate file-based test benches and compare the test results for the MATLAB and C implementations;

•Integrate the handwritten C code using the MEX API specification so that it may be directly called from within MATLAB and use test benches in MATLAB to exercise the MEX function and verify its result.

While the latter approach is more efficient and streamlined, the task of writing a MEX wrapper function that passes data between MATLAB and the C code can be tedious and error-prone. If care is not taken to allocate memory properly and perform proper error checking in the MEX wrapper code, then memory integrity violations can occur during the MEX function execution in MATLAB, potentially causing unpredictable results or a crash.

With the automated workflow, the MEX function can be automatically generated from the MATLAB algorithm that has been prepared for code generation. Engineers can use this step to determine if the modifications they made to the MATLAB code in preparation for code generation were sufficient.

Once the MEX function is successfully generated (indicating the preparation step was successful), it can be used to catch any potential design issues that might show up in the compiled code, such as unauthorised memory access or numerical inaccuracies introduced by the C/C++ compiler.

This functional verification step confirms that the MATLAB code is finally ready for C source code generation.

Because the automatically generated MEX functions are com-piled versions of MATLAB algorithms, in some cases they may execute faster in MATLAB than the original algorithms, depending on the nature of the algorithms implemented.

After functionally verifying that the MEX functions are equivalent to their source MATLAB algorithms, engineers can turn off memory integrity checks and other options that may slow execution and then regenerate MEX functions that are further optimised for performance.

These functions can then be used in place of the original MATLAB algorithms to accelerate execution.

At this point, engineers may also generate C source code (as .c, .cpp, and .h files) that can then be compiled into a library or a stand-alone executable or integrated into other development projects written in C/C++. The code produced by MATLAB Coder is commented and readable, so that it can be readily understood.

The generated code can be optimised by modifying the MAT-LAB source code or by adjusting code generation settings that effect readability or performance.

Automatically generating readable and portable C code from MATLAB algorithms is an easy and efficient way to speed up the system design to implementation workflow. Preparation of the code requires introducing implementation requirements, pre-allocating variables and using the supported subset of the MATLAB language.

After assessing the generated C code, MATLAB algorithms can be refined and code can be regenerated in minutes. The results of the compiled code can be verified against the origi-nal golden reference MATLAB code. This quick iteration cycle enables engineers to converge on the desired C implementation while letting them work in MATLAB longer.

The result is a sharper focus on more efficient and optimised algorithm creation and less time spent on programming details in a lower level language.
