Output-on Phase Control (Sequence 2: SYNChronize)

Using TRIGger:SEQuence2 (or TRIGger:SYNChronize) subsystem allows you to synchronize the output ON/OFF changes with a specific AC output phase angle.

 

:TRIGger:SEQuence2:SOURce PHASe   'Selects PHASe trigger
:TRIGger:SEQuence2:PHASe 270   'Sets the phase angle at 270 deg
:OUTPut ON   'Turns the output on

 

When the power supply output is changed from OFF to ON state, the changing action is synchronized to the specified phase angle.

To disable the output-on phase control, set the trigger source to IMMediate.

 

:TRIGger:SEQuence2:SOURce IMMediate

 

The output-on phase control is applied only when the output is changed from OFF to ON.

It is not applied when the output changes from ON to OFF or when other settings such as the AC voltage setting, DC voltage setting, and frequency setting change.

The output-on phase control is not a function that synchronizes the output frequency to the input commercial AC line.

The sequence 2 group does not have INITiate commands. It is always initiated and cannot be aborted.
