Explanation  When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related
parameters of CH1 by default.
 AM (Amplitude Modulation): the amplitude of the carrier waveform changes
with the transient voltage of the modulating waveform.
 FM (Frequency Modulation): the frequency of the carrier waveform changes
with the transient voltage of the modulating waveform.
 PM (Phase Modulation): the phase of the carrier waveform changes with the
transient voltage of the modulating waveform.
 ASK (Amplitude Shift Keying): the signal generator shifts the output amplitude
between two preset amplitudes (the carrier amplitude and modulation
amplitude).
 FSK (Frequency Shift Keying): the signal generator shifts the output frequency
between two preset frequencies (the carrier frequency and hop frequency).
 PSK (Phase Shift Keying): the signal generator shifts the output phase
between two preset phases (the carrier phase and modulation phase).
 PWM (Pulse Width Modulation): the carrier pulse width changes with the
transient voltage of the modulating waveform.
Return Format The query returns AM, FM, PM, ASK, FSK, PSK or PWM.
Example :SOUR1:MOD:TYPE FM /*Set the modulation type of CH1 to FM*/
:SOUR1:MOD:TYPE? /*Query the modulation type of CH1 and the query
returns FM*/
