Command Syntax

:TRIGger:PLOCk  {ON | OFF | 1 | 0}

Query Syntax

:TRIGger:PLOCk?

Query Response

{1 | 0}

Description

Turns on or off pattern locking, which generates a pattern trigger. After turning on pattern locking, use the :SYSTEm:PAUTodetect command to automatically detect symbol rate, pattern length, and the trigger divide ratio. If any of these three waveform parameters are manually specified, the parameter will not be automatically detected by :SYSTem:PAUTodetect. To turn on automatic detection of the symbol rate, use the :TRIGger:SRATe:AUTodetect command. To turn on automatic detection of the pattern length, use the :TRIGger:PLENgth:AUTodetect command. To turn on automatic detection of the trigger divide ratio :TRIGger:DCDRatio:AUTodetect command.

Use of an *OPC? query to pause program execution while waiting for this command to execute.

Common Numerical Child Commands

This command supports the use of the following common numerical child commands: :DEFault, :MAXimum, :MINimum, and :STEP.

For the :STEP child command, positive integers increase the setting; negative integer decrease the settings.
