[:SOURce[]][:MOD]:FM:STATe
Syntax [:SOURce[]][:MOD]:FM:STATe {ON|1|OFF|0}
[:SOURce[]][:MOD]:FM:STATe?
Description Turn on or off the FM modulation function of the specified channel.
Query the on/off status of the FM modulation function of the specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
{ON|1|OFF|0} Bool ON|1|OFF|0 OFF
Explanation  FM (Frequency Modulation): the frequency of the carrier waveform changes with
the transient voltage of the modulating waveform.
 The FM carrier waveform could be Sine, Square, Ramp or Arbitrary waveform
(except DC). The default is Sine. Pulse, Noise and DC in the arbitrary waveform
could not be used as carrier waveform. The different settings of various
parameters (such as the frequency, amplitude, offset and start phase) of the
carrier waveform will influence the FM modulated waveform.
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
 If the sweep function ( [:SOURce[]]:SWEep:STATe ) or burst function
( [:SOURce[]]:BURSt[:STATe] ) is currently enabled, it will be disabled
automatically when the modulation function is turned on.
 If the harmonic function is currently enabled
( [:SOURce[]]:HARMonic[:STATe] ), the modulation function cannot be turned
on (namely the harmonic cannot be modulated).
Return Format The query returns ON or OFF.
Example :SOUR1:FM:STAT ON /*Turn on the FM modulation function of CH1*/
:SOUR1:FM:STAT? /*Query the on/off status of the FM modulation function of
CH1 and the query returns ON*/
