Command system EN Reset all phase generators in the instrument to establish a zero-reference point of universal internal phases. Argument None Instructions ⚫ SOURce1 and SOURce2 are meaningliess for this command. ⚫ This setting is not valid when either of the two channels is in modulation mode. Return format None Example PHAS:SYNC /* Reset all phase generators */ 3.19 PM subsystem PM subsystem enables you to modulate waveforms via phase. 3.19.1 SOURce :MOD:PM:DEViation Command format SOURce :MOD:PM:DEViation |MINimum|MAXimum SOURce :MOD:PM:DEViation? [MINimum|MAXimum] Function description Set the phase deviation in degrees.
This value represents the peak phase change of the modulated waveform with respect to the carrier waveform. Argument Instructions With an external modulation source, the deviation is controlled by the ± 5 V signal level displayed on the MOD connector on the front panel. For example, if you have set the frequency deviation to 180 degrees, a +5 V signal level is equivalent to a +180 phase deviation. A lower external signal level produces a smaller deviation, and a negative signal level produces a negative deviation.
