output from the Ext Trig connector on the rear panel at the beginning of the
sweep or burst.
OUTPut:TRIGger?
“0” or “1” indicating the trigger out signal state will be returned.

PHASe {<angle>
︱ MINimum ︱ MAXimum}
Adjust the phase offset of the output waveform in degrees or radians as
specified by the previous UNIT:ANGL command (not available for pulse and
noise). The range is form -360 degrees to 360 degrees or -2∏ to +2∏ radians.
The default is 0 degrees.
z
The specified phase adjustment causes a “bump” or “hop” in the output
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.
