waveform in order to change the phase relationship to the external signal
to which it is currently locked.
z
The phase adjustment for phase-lock applications is independent of the
burst phase as set by the BURS:PHAS command.
PHASe [MINimum
︱
MAXimum]
Query the phase offset in degree or radians.
PHASe:REFerence
Set the zero-phase reference point immediately without changing the output.
This command changes the phase reference only, and it does not change the
phase offset as set with the PHAS command.
PHASe:UNLock:ERRor:STATe {OFF
︱
ON}
Disable or enable the waveform generator to generate an error when the
phase-lock is lost. The default is off. When the error is enabled, and the
phase-lock is lost, a ”Reference phase-lock loop is unlocked” error will be
generated. The error setting is cleared after the waveform generator has been
turned off.
PHASe:UNLock:ERRor:STATe?
Query the enable state of the lost phase-lock error.
PM:INTernal:FUNCtion
{SINusoid|SQUare|RAMP|NRAMP|TRIangle|NOISe|USER}
Specify the shape of the modulating waveform. This applies only when the
modulation source is Internal (PM:SOUR INT). Noise can be a modulating
waveform, but cannot be used as a carrier waveform, neither do Pulse nor dc.
The default modulating waveform is a sine waveform.
-- Square waveform has 50% duty cycle.
--Ramp waveform has 100% symmetry
--Triangle waveform has 50% symmetry.
--Negative Ramp waveform has 0% symmetry.
--If an Arbitrary(USER) waveform is chosen to be the modulating waveform, it is
automatically limited to 4k points. Extra points are removed using decimation.
