Accuracy (when 3930A is in
CONT mode)
-360" to 360" (Value corresponding to 0" at 3930A's start/stop phase)
Maximum 4 digits f resolution 0.1' (futed)
o Set both 3930A and 3933A to these settings:
DC offset OV, AM off, 5OQ load, same waveform, 18°-280C.
o Waveform duty cycle is fixed or variable on both devices. (cycle is optional)
o Amplitude setting is between 3O.OmVp-p to 3O.OVp-p,
and can be set independently.
o When connecting in sequence, phase number n is per this diagram:

n=l n=2 n=3
However, n < 6 (to max of 6 phases)
