Description
Set or query the modulating waveform of AM or FM of the specified source channel.
Parameter
Name Type Range Default
[<n>] Discrete {1|2}
If omitted, the operation is
performed on source 1 by
default
<wave> Discrete {SINusoid|SQUare|RAMP|NOISe} SINusoid
Explanation  Sine (SINusoid), Square (SQUare), Ramp (RAMP) or Noise (NOISe) can be selected
as the modulating waveform. You can set the frequency of the modulating
waveform by sending
[:SOURce[<n>]]:MOD:AM:INTernal:FREQuency or
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency.
 Sending the
[:SOURce[<n>]]:MOD:TYPe command can set the modulation type.
 AM: amplitude modulation. The amplitude of the carrier waveform varies with the
amplitude of the modulating waveform.
FM: frequency modulation. The frequency of the carrier waveform varies with the
amplitude of the modulating waveform.
Return Format
The query returns SIN, SQU, RAMP or NOIS.

:MOD:AM:INTernal:FUNCtion SQUare
[:SOURce[<n>]]:MOD:FM[:DEVIation]
Syntax [:SOURce[<n>]]:MOD:FM[:DEVIation] <dev>
[:SOURce[<n>]]:MOD:FM[:DEVIation]?
Description Set or query the FM frequency deviation of the specified source channel. The default unit
is Hz.

0Hz to the carrier waveform
frequency
10kHz
Explanation  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”.
Return Format
The query returns an integer.
Example
:MOD:FM 100
