:LTESt:LLINe:SWAVeform:DIFF{N}:STATe

Command Syntax

:LTESt:LLINe:SWAVeform:DIFF{N}:STATe {DISK | MEMory | OFF}

{N} identifies the differential waveform, which must be selected from {1:8}{A|C}. For example, the differential waveform of channels 1A and 2A would be identified as DIFF1A.

Query Syntax

:LTESt:LLINe:SWAVeform:DIFF{N}:STATe?

Description

Specifies the reporting action for the selected differential waveform upon completion of limit testing for a limit line test. Use the command argument to select or turn off the reporting action. To disable the reporting action of all channel, common-mode, differential, and function waveforms, use the :LTEST:LLINe:SWAVeform:RESet command.

To turn on limit testing for a limit line test, use the :LTESt:LLINe:TEST:STATe command.

Command Arguments

Argument	Description
DISK	Saves the waveform to a file (.wfmx) in the %USER_DATA_DIR%\Limit Lines folder. Use the :LTESt:LLINe:SWAVeform:DIFF:FNAMe command to specify the file name.
MEMory	Saves the waveform to a memory location. Use the :LTESt:LLINe:SWAVeform:DIFF:WMEMory command to specify the memory location.
OFF	Turns off the saving of a differential waveform.
