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.
