APPLy:USER?
Response
The PXA125 will return <seg#>,<sclk>, <ampl>,<offs>. Default values are 1,10e6,5,0
FM{OFF|ON|0|1}
Purpose
This command will turn the FM function on and off.
•
ON or 1 will set the FM on
•
OFF or 0 will set the FM off

Response and default
The PXA125 will return 1 if the FM is on, or 0 if the FM is off. Default is 0.
FM:DEViation<deviation>
Purpose
This command will set the deviation frequency in units of samples per second.
•
<deviation> sets the phase offset between the channels. Phase offset is in waveform points
Parameter type
Numeric
Parameter range
<deviation> 1e-3 to 100e6 in units of samples per second
FM:DEViation?
Response and default
The PXA125 will return the present frequency deviation value. The returned value will be in standard scientific
format (for example: 100mHz would be returned as 100E-3 – positive numbers are unsigned). Default value
is 1e3. Default value is 1e6.
FM:FUNCtion:MODE{FIXed|USER}
Purpose
This command will set the frequency modulating waveform mode to FIXed (standard) and USER (arbitrary)
