Trigger[:Edge]:Coupling - Keysight Technologies InfiniiVision 4000 X Series Programmer's Manual

:TRIGger[:EDGE]:COUPling

Command Syntax
:TRIGger[:EDGE]:COUPling <coupling>
<coupling> ::= {AC | DC | LFReject}
The :TRIGger[:EDGE]:COUPling command sets the input coupling for the selected
trigger sources. The coupling can be set to AC, DC, or LFReject.
• AC coupling places a high-pass filter (10 Hz for analog channels, and 3.5 Hz for
• LFReject coupling places a 50 KHz high-pass filter in the trigger path.
• DC coupling allows dc and ac signals into the trigger path.
The :TRIGger[:EDGE]:COUPling and the :TRIGger[:EDGE]:REJect selections are coupled.
N OTE
Changing the setting of the :TRIGger[:EDGE]:REJect can change the COUPling setting.
Query Syntax
:TRIGger[:EDGE]:COUPling?
The :TRIGger[:EDGE]:COUPling? query returns the current coupling selection.
Return Format
<coupling><NL>
<coupling> ::= {AC | DC | LFR}

the trigger waveform. Use AC coupling to get a stable edge trigger when your
waveform has a large dc offset.
