DUT RF Power Measurements
1. Consult the DUT
manufacturer’s manual for load specifications.
2. Remove all connections between the DUT and the ESU-2000A Analyzer.
3. Install the Switching Module on the ESU-2000A front panel so that the w
ords “ESU
Power Testing” are right-side-up. When installed correctly, the Active Electrode
connectors should be exposed, and the RF Leakage connectors should be
inaccessible.
4. Connect a single electrode REM cable from the ESU-2000A terminal labeled
“Patient Plate” to the DUT’s Patient Plate or Return Electrode.
5. Connect a yellow safety lead from the DUT
’s RF Active Output to the desired load
terminal of the ESU-2000A. The Active Electrode input connectors are color coded,
and each corresponds to a color-coded range on the analog meter.
6. Set the DUT for proper output mode and power level, being careful that the power
setting does not exceed the full-scale Power range selected on the ESU-2000A.
7. Activate the DUT output. The Analyzer will indicate both mA RMS and Power (W)
on the appropriate color-coded wattage meter range.
8. Deactivate the DUT output before disconnecting from ESU-2000A, or before moving
the Active Electrode test lead to a different input range connector.
DUT RF Leakage Current Measurements
1. Remove all connections between the DUT and the ESU-2000A Analyzer.
2.
Install the Switching Module on the ESU-2000A front panel so that the words
“RF
Leakage Testing” are right-side-up. When installed correctly, the Active Electrode
connectors should be inaccessible, and the RF Leakage connectors should be
exposed.
3.
Connect a yellow safety lead from the ESU-
2000A terminal labeled “RF Leakage” to
the DUT’s RF Active Output. DO NOT MEASURE ACTIVE ELECTRODE LEAKAGE
ON NON-ISOLATED ESUs with the ESU-2000A. Damage may occur to the ESU-
2000A.
