SOURce1:PM1:RATio 40
SOURce1:PM1:MODE HBAN
// Alternatively configure the phase modulation settings for an
// external modulation source and query the input sensitivity.
SOURce1:PM1:SOURce EXT1
// SOURce1:PM1:SOURce EXTernal
SOURce1:PM1:DEViation 1
SOURce1:PM1:SENSitivity?
// Response: 1
// since the voltage value for full modulation is 1V,
// the resulting sensitivity is precisely 1RAD/V.
// Activate the signal output
SOURce1:PM1:STATe 1
OUTPut1:STATe 1
Example: Using combined LF signals
Using the internal LF generators of both paths, the following command sequences con-
figure an phase modulated signal with determined deviations.
// Configure the Phase modulation settings with combined LF signal sources
SOURce1:PM1:SOURce LF1
SOURce1:PM1:DEViation 1.5
// Select the modulation signal source for the second path
SOURce1:PM2:SOURce LF2
// Combine the signals of both paths with fixed total deviation depth
SOURce1:PM1:DEViation:MODe TOT
SOURce1:PM1:DEViation:SUM 2
// Query the deviation depth of the modulation signal in the second path
SOURce1:PM2:DEViation?
// Response: 0.5
// Combine the signals of both paths with fixed ratio
SOURce1:PM1:DEViation:MODe RAT
SOURce1:PM1:RATio 80
SOURce1:PM2:DEViation?
// Response: 1.2
// Query the deviation depth of modulation signal in the first path
SOURce1:PM1:DEViation?
// Response: 1.5
SOURce1:FM1:STATe 1
SOURce1:FM2:STATe 1
