[:SOURce[<n>]]:MOD:FM[:DEVIation]
[:SOURce[<n>]]:MOD:FM[:DEVIation] <dev>
[:SOURce[<n>]]:MOD:FM[:DEVIation]?
Set or query the FM frequency deviation of the specified source channel. The default unit
is Hz.
If omitted, the operation is
performed on source 1 by
default
0Hz to the carrier waveform
frequency
 Sending [:SOURce[<n>]]:FREQuency[:FIXed] can set the carrier waveform
frequency and sending [:SOURce[<n>]]:MOD:FM:INTernal:FREQuency can set the
FM modulation frequency.
 When the modulating waveform amplitude reaches its maximum, the carrier
waveform frequency increases by the "frequency deviation". When the modulating
waveform amplitude reaches its minimum, the carrier waveform frequency
decreases by the "frequency deviation".
 You can only set the FM frequency deviation when the modulation type of the
specified signal source channel is set to FM.
The query returns an integer.
:MOD:FM 100 /*Set the FM frequency deviation of source 1 to 100Hz*/
:MOD:FM? /*The query returns 100*/
[:SOURce[<n>]]:APPLy?
Query the output configurations of the specified source channel.
If omitted, the operation is
performed on source 1 by
default
The query returns the output configurations in "<waveform
name>,<frequency>,<amplitude>,<offset>,<start phase>" format. If the
corresponding parameter does not exist, it will be replaced by "DEF".
:APPLy? /*The query returns SIN,1000.000000,1.000000,0.000000,0.000000*/
