SCPI Programming Reference
HDG2000 Series Arbitrary Waveform Generator 87
Sets the phase in degrees.
0 to 360 degrees, default 180 degree
Sets the phaseon CH1 to 90degrees: SOURce1:MOD:PSKey:PHASe 90
SOURce<n>:MOD:PSKey:INTernal:RATE <frequency>|MINimum|MAXimum
SOURce<n>:MOD:PSKey:INTernal:RATE? [MINimum|MAXimum]
Set the “mobile” rate of output frequency between carrier frequency and hopping frequency.
2 mHz to 1 MHz, default 100Hz
Set PSK rate on CH1 to 200Hz: SOURce1:MOD:PSKey:INTernal:RATE 200
SOURce<n>:MOD:PSKey:SOURce INTernal|EXTernal
SOURce<n>:MOD:PSKey:SOURce?
Select the source(INTrnal or EXTenal) of the modulating signal.
INTernal|EXTernal, default INTernal
Select external modulation source for CH1: SOURce<n>:MOD:FSKey:SOURce EXTernal
SOURce<n>:MOD:PSKey:POLarity POSitive|NEGative
SOURce<n>:MOD:PSKey:POLarity?
Select POSitive or NEGative of the modulating signal to control waveform output.
POSitive|NEGative, default POSitive
Set NEGative of ASK modulating signal on CH1: SOURce1:MOD:PSKey:POLarity NEGative
5.2.22 PWM Subsystem
The PWM subsystem allows you to perform pulse width modulation (PWM) on a pulse waveform.
SOURce<n>:MOD:PWM:DEViation <deviation>|MINimum|MAXimum
SOURce<n>:MOD:PWM:DEViation? [MINimum|MAXimum]
Sets pulse width deviation; the ± variation in width (in seconds) from the pulse width of the carrier
pulse waveform.
0 ns to 500 ks, default 200μs
Set pulse width deviation to1s: SOURce1:MOD:PWM:DEViation 1
The pulse width deviation cannot exceed the current pulse width
The pulse width deviation is limited by the current edge time setting.
SOURce<n>:MOD:PWM:INTernal:FREQuency <frequency>|MINimum|MAXimum
SOURce<n>:MOD:PWM:INTernal:FREQuency? [MINimum|MAXimum]
