Chapter 2 Command System
When the modulating waveform amplitude reaches the maximum value, the
frequency of the carrier is increased by "frequency offset". When the modulating
waveform amplitude reaches the minimum value, the frequency of the carrier is
decreased by "frequency offset".
Only when FM is selected for the specified function/arbitrary waveform generator
channel, can the frequency offset of FM be set.
Return
The query returns the frequency offset in scientific notation.

[:SOURce[<n>]]:APPLy?
Syntax
[:SOURce[<n>]]:APPLy?
Description
Queries the current output configuration of the specified function/arbitrary waveform
generator channel.
Parameter
Name
[<n>]
Return
The query returns the current output configuration in "<waveform

name>,<frequency>,<amplitude>,<offset>,<start phase>" format. If no
corresponding parameter is found, DEF is replaced with the specified parameter value.
