11 4. Radiated Emissions tests Test Equipment EMT 3m site in Inniscarra, Co. Cork. Biconical Antenna -Eaton (S/N 1220) Log periodic Antenna - EMCO 3146 (S/N ) Advantest Spectrum Analyser R3361A (S/N ) Rhode and Schwarz ESVS 30 receiver (S/N /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 EN 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.

HP 8648A Signal Generator (S/N 3625U0058) Agilent 54616B Oscilloscope (S/N US ) ENI model 310L RF Power Amplifier 50dB linear (S/N 483) Prodigit Electronics Power and Energy Monitor 2000MU (S/N SG19123) Conducted Immunity test method The test method used was direct injection onto the mains cord. This test method is described in EN and the limits are defined in EN 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.
