Command system EN Instructions This command can only be used with internal modulation sources (PM:SOURce INTernal). Return format SINusoid, SQUare, or RAMP. Example SOURce1:MOD:PM:INTernal:FUNCtion SQUare /* Set the waveform shape of Channel 1 modulated wave to square wave */ 3.19.4 SOURce :MOD:PM:SOURce Command format SOURce :MOD:PM:SOURce INTernal|EXTernal SOURce :MOD:PM:SOURce? Function description Select AM modulation source type as internal (INTernal) or external (EXTernal). Argument Instructions None Return format INTernal or EXTernal.
Example SOURce1:MOD:FM:SOURce EXTernal /* Set the modulation source of channel 1 to external */ 3.20 PSK subsystem PSK (Phase Shift keying) A modulation technique in which the input signal information is represented by the carrier phase.
