The query returns the current duty cycle in scientific notation.
:PULSe:DCYCle 50 /*Sets the duty cycle of GI pulse to 50%.*/
:PULSe:DCYCle? /*The query returns 5.000000E+1.*/
[:SOURce[<n>]]:MOD:TYPE
[:SOURce[<n>]]:MOD:TYPE <type>
[:SOURce[<n>]]:MOD:TYPE?
Sets or queries the modulation type of the specified function/arbitrary waveform
generator channel.
When omitted, by default, the operations are
carried out on GI.
 AM: Amplitude Modulation. The amplitude of the carrier waveform changes with the
amplitude of the modulating waveform.
FM: Frequency Modulation. The frequency of the carrier waveform changes with the
the modulating waveform.
FSK: Frequency-shift Keying Modulation. Control the carrier frequency changes with
the digital signal.
 The Sine, Square, Ramp, Built-in Waveform, or Non-DC signal's arbitrary waveforms
can be regarded as carrier waveforms.
 You can select Sine, Square, Triangle, or Noise as the modulating waveforms.
The query returns AM, FM, or FSK.
:MOD:TYPE AM /*Sets the modulation type of GI to AM.*/
:MOD:TYPE? /*The query returns AM.*/
[:SOURce[<n>]]:MOD:AM[:DEPTh]
[:SOURce[<n>]]:MOD:AM[:DEPTh] <depth>
[:SOURce[<n>]]:MOD:AM[:DEPTh]?
Sets or queries the depth of AM of the specified function/arbitrary waveform
generator channel. The modulation depth refers to the strength of the AM and is
expressed in percentage.
When omitted, by default, the operations
are carried out on GI.
 When the modulation depth is 0%, the output amplitude is half of the amplitude
of the carrier signal.
 When the modulation depth is 100%, the output amplitude is equal to the
amplitude of the carrier signal.
