n:AM:DEPth
10.0 sets the modulation depth to 10%.
AFG:MODULation:AM:FREQuency
Description:
Sets the modulation frequency to use for Amplitude Modulation for the AFG.
Conditions:
Beta Command, see conditions of use. Default setting is 10.0E+3.
Group:
AFG
Syntax:
AFG:MODULation:AM:FREQuency <NR3>
AFG:MODULation:AM:FREQuency?
Arguments:

Examples:
AFG:MODULation:AM:WAVeform SINE sets the modulation waveform to SINE.
AFG:MODULation:FM:DEViation
Description:
Sets the mod
ulation deviation to use for Frequency Modulation for the
AFG. This value is the deviation around the center frequency specified in
AFG:MODULation:FM:FREQuency
.
Conditions:
Beta Comm
and, see conditions of use
. Default setting is 50.0.
Group:
AFG
Syntax:
AFG:MODULation:FM:DEViation <NR3>
AFG:MODULation:FM:DEViation?
Arguments:
<NR3> - Deviation value in Hz from 0.0 to 25.0E+6 with a resolution of 0.1Hz.
Maximum value is half the frequency maximum specified by the shape chosen
using AFG:FUNCtion.
Examples:
AFG:MODULation:FM:DEViation 10.0E+3 sets the modulation depth to 10kHz.
AFG:MODULation:FM:FREQuency
Description:
Sets the modulation frequency to use for Frequency Modulation for the AFG.
Conditions:
Beta Command, see conditions of use. Default setting is 10.0E+3.

{SINE|SQUare|TRIangle|RAMP|NRAMP|NOISe}
AFG:MODULation:FM:WAVeform?
Arguments:
SINE -Sinewaveform
SQUare - Square waveform
TRIangle - Triangle waveform
RAMP - Positive ramp waveform
NRAMP - Negative ramp waveform
NOISe - Noise waveform
Examples:
AFG:MODULation:FM:WAVeform SINE sets the modulation waveform to SINE.
AFG:MODULation:TYPe
Description:
Sets the modulation type for the AFG. AFG:RUNMode must be set for types
to be set. The command will return NONe unless AFG:RUNMode
is set to
MODUlation.
Conditions:
Beta Command, see conditions of use. Default setting is NONe.
