[:SOURce<hw>]:PM:DEViation:MODE <PmDevMode>
Selects the coupling mode. The coupling mode parameter also determines the mode
for fixing the total deviation.
Parameters:
<PmDevMode> UNCoupled | TOTal | RATio
UNCoupled
Does not couple the LF signals.
The deviation values of both paths are independent.
TOTal
Couples the deviation of both paths.
RATio
Couples the deviation ratio of both paths
*RST: UNCoupled
Example: See Example "Using combined LF signals" on page 577
Manual operation: See " Deviation Mode" on page 89
[:SOURce<hw>]:PM:DEViation:SUM <PmDevSum>
Sets the total deviation of the LF signal when using combined signal sources in phase
modulation.
Parameters:
<PmDevSum> float
Range: 0 to 20
Increment: 1E-6
*RST: 1
Example: See Example "Using combined LF signals" on page 577
Manual operation: See " Total Deviation" on page 90
[:SOURce<hw>]:PM:RATio <Ratio>
Sets the deviation ratio (path2 to path1) in percent.
Parameters:
<Ratio> float
Range: 0 to 100
Increment: 0.01
*RST: 100
Example: See Example "Performing phase modulation" on page 577.
Manual operation: See " Ratio Path2/Path1" on page 90
[:SOURce<hw>]:PM:SENSitivity?
Queries the sensitivity of the externally applied signal for phase modulation.
