4.1. Test Equipment EMT 3m site in Inniscarra, Co. Cork. Biconical Antenna -Eaton 94455-1 (S/N 1220) Log periodic Antenna - EMCO 3146 (S/N 9210-3462) Advantest Spectrum Analyser R3361A (S/N 11730606) Rhode and Schwarz ESVS 30 receiver (S/N 826006/004) 10m UHF cable with ferrites (S/N EMT#008) Hewlett Packard 8447F amplifier. (S/N 3113A06542)

4.2. Measurements Tests were performed in accordance with the radiated emissions aspect of EN55022. Limits at 3m are 10dB above those at 10m. Note: when reading the measurements noted on the site on the day it is necessary to compare the ambient signals for the site also. These ambient signals are signals that are present even when the EUT is removed. A final measurement is taken in QP and that is the level compared against the limits. QP reading are either the same as, or less, than peak readings. The graphs show peak readings. The receiver is used to measure the QP level after the signal has been noted in the peak graph. Any signals over the limit in the graphs were verified by EMT as being ambient signals. VHF is used to designate use of the Eaton antenna (30MHz to 200MHz) and UHF is used to designate use of the Log-periodic antenna (200MHz to 1GHz) Emissions when running in 600W and 1200W were the same.

4.7.2. Surge Testing Test Method

Tests were performed in accordance with IEC 61000-4-5 referred to by EN 61000-6-2. Performance criteria allow the EUT to deviate from normal operation during application of the interference, but the unit must resume normal operation in the original state after application of the interference. The scope was used to check the output of the test generator. Levels of interference are ±2kV Line 1 and 2 to Earth and ±1kV Line1 to Line2 (Live to neutral).

4.9.2. Conducted Immunity test method

The test method used was direct injection onto the mains cord. This test method is described in EN61000-4-6 and the limits are defined in EN 61000-6-2 The test comprised setting up the cable to have 150Ω termination at both ends and then injecting a signal into either the direct coupler or the electromagnetic clamp. The power level on the 8648A AM frequency generator needed to get 10V on the cable was noted for each frequency. The power cable was now attached to the injection box and the noted levels applied to the RF port.

4.10.2. Test Method, Interference Levels & Performance Criteria

This test is performed in accordance with the basic standard EN61000-4-3 referred to by EN 61000-6-2 This is a substitution method and the levels were determined by first radiating the isotropic antenna after placing it in the same position as the EUT would be during the tests. After noting the power required to give RF levels of 10V/m at the EUT, the isotropic antenna was removed and replaced with the EUT.

Frequency range Modulation Level Dwell time 80 MHz to 2.5GHz 80% 10V 2.8 secs

4.10.3. Results No variation was noted in the input wattage to the EUT.
