5.8 Measurement Accuracy
5.8.1 Measurement Mode IMPD
−EXT and G−PH
The conditions are that ambient temperature of 0 to +40°C, within 12 hours since
self-calibration was performed after warming up for at least 30 minutes, and ambient
temperature variations are within ±5°C after self-calibration.
DUT drive amplifier gain setting K = +1.0 and input weighting factor is 1.0 for both
PORT1
and
PORT2
.
