4.0 Radiated and Conducted Emissions

4.1 Radiated Emissions

4.1.1 Radiated Emissions Test Site

4.1.1.1 Open Area Test SiteThe open area test site consists of a 40 x 66 concrete pad covered with a perforated electro-platedgalvanized sheet metal. The perforations in the sheet metal are 1/8 holes that are staggered every3/16. The individual sheets are placed to overlap each other by 1/4 and are riveted together to providea continuous seam. Rivets are spaced every 3 in a 3 x 20 meter perimeter around the antenna mastand EUT area. Rivets in the remaining area are spaced as necessary to properly secure the groundplane and maintain the electrical continuity.

The entire ground plane extends 12 beyond the turntable edge and 16 beyond the antenna mast whenset to a 10 meter measurement distance. The ground plane is grounded via 4 - 8 copper ground rods,each installed at a corner of the ground plane and bound to the ground plane using 3/4" stainless steelbraided cable.

The turntable is an all aluminum 10 flush mounted table installed in an all aluminum frame. The table isremotely operated from inside the control room located 40 from the range. The turntable is electricallybonded to the surrounding ground plane via steel fingers installed on the edge of the turn table. The steelfingers make constant contact with the ground plane during operation.

Adjacent to the turntable is a 7 x 7 square and 4 deep concrete pit used for support equipment ifnecessary. The pit is equipped with 5 - 4 PVC chases from the pit to the control room that allow forcabling to the EUT if necessary. The underside of the turntable can be accessed from the pit so cablescan be supplied to the EUT from the pit. The pit is covered with 2 sheets of 1/4" diamond style re-enforced steel sheets. The sheets are painted to match the perforated steel ground plane; however theunderside edges have been masked off to maintain the electrical continuity of the ground plane. Allreflecting objects are located outside of the ellipse defined in ANSI C63.4.

4.1.1.2 Semi-Anechoic ChamberThe Semi-Anechoic Chamber Test Site consists of a 20 x 30 x 18 shielded enclosure. The chamber islined with Toyo Ferrite Grid Absorber, model number FFG-1000. The ferrite tile grid is 4 x 4 x thickand weighs approximately 1.4lbs. These tiles are mounted on steel panels and installed directly on theinner walls of the chamber.

The turntable is 150cm in diameter and is located 160cm from the back wall of the chamber. Thechamber is grounded via 1 - 8 copper ground rod, installed at the center of the back wall, it is bound tothe ground plane using 3/4" stainless steel braided cable.

The turntable is all steel, flush mounted table installed in an all steel frame. The table is remotelyoperated from inside the control room located 25 from the turntable. The turntable is electrically bondedto the surrounding ground plane via steel fingers installed on the edge of the turn table. The steel fingersmake constant contact with the ground plane during operation.

Behind the turntable is a 3 x 6 x 4 deep shielded pit used for support equipment if necessary. The pit isequipped with 1 - 4 PVC chase from the turntable to the pit that allow for cabling to the EUT if necessary.The underside of the turntable can be accessed from the pit so cables can be supplied to the EUT fromthe pit.

4.1.1.3 Fully Anechoic ChamberThe 3m fully anechoic chamber is used for pre-screening the EUT for emissions only. Final screening isperformed on the OATS or in case of Class B EUTs, in the 3m semi-anechoic chamber. The FullyAnechoic Chamber has been characterized for field uniformity in accordance with IEC 61000-4-3 and canbe used for final radiated fields immunity testing.

The Fully-Anechoic Chamber Test Site consists of a 24L x 16W x 12H shielded enclosure. Thechamber is fully lined with RF absorbing foam. The foam ranges in type from 8-24 conventionalpyramidal cones, 8-12 conventional wedges and 6 and 16 Hybrid Foam over ferrite tile. The Hybridmaterial is placed in the 6 specular regions of the chamber for better low-frequency performance. Thespecular regions are 1) directly behind the receiving antenna, 2) on the floor between the receivingantenna and the EUT table, 3) the wall directly behind the EUT, 4&5) the side walls between the receivingantenna and the EUT table and 6) the ceiling between the receiving antenna and the EUT. The specularregions are 6 x 4 in size.

The chamber is grounded via 1 - 8 copper ground rod, installed at the center of the back wall, it is boundto the shield using 3/4" stainless steel braided cable.

The turntable is a remotely controlled EMCO Model 1060 and is 150cm in diameter and is located 1mfrom the absorber on the back wall of the chamber.

4.1.3 Test Methodology

4.1.3.1 Pre-ScansRadiated pre-scans are performed on all EUTs in either the 3m Semi-Anechoic or the 3m Fully-AnechoicChamber. Final emission testing for Class A equipment is performed on the 3/10m Open Area Test Site(OATS) as described in section 4.1.1. Final emission testing on Class B equipment can be performed

either in the 3m Semi-Anechoic chamber described in section 4.1.2 or on the OATS.

Pre-scans are a method by which the 10 highest emissions can be identified for final evaluation. This isachieved by taking automated emission snapshots of the EUT at various azimuths and antenna heights.The software is programmed to perform a peak sweep of the band using the maxhold function. Thissweep is performed every 90 in both horizontal and vertical polarities and at antenna heights of 100cmand 300cm. Although not a fully maximized scan, the pre-scan gives a good indication of pass or fail.

4.1.3.2 Final ScansRadiated emissions measurements were made over the frequency range of 30MHz to 1000MHz. Quasi-Peak measurements are taken with the Spectrum Analyzers resolution bandwidth was set to 120KHzand video bandwidth set to 300 kHz for measurements below 1000MHz. Average measurements aretaken with the RBW and VBW were set to 1MHz and 10 Hz for measurements above 1000MHz. The

calculation for the radiated emissions field strength is as follows:

Corrected Reading = Analyzer Reading + Cable Loss + Antenna FactorMargin(dB) = Applicable Limit - Corrected Reading

4.1.3.3 Test CriteriaThe EUT must meet the Class B Limits as given in section 1.4.1.

4.1.3.4 Test Justification

No justification - The EUT was tested per the appropriate test methods and test plan.The test method, standard, and/or test plan was deviated from for the following reason:
