DC
Explanation
This command is only applicable to edge trigger of which the signal source is an
analog channel.
AC: block all the DC components and attenuate signals lower than 75 kHz.
DC: allow DC and AC components into the trigger path.
LFReject: block the DC components and reject the low frequency components (lower
than 75 kHz).
HFReject: reject the high frequency components (higher than 75 kHz).
Return
Format
The query returns AC, DC, LFR, or HFR.
Example
:TRIGger:COUPling LFReject /*Set the trigger coupling type to low-frequency
rejection*/
:TRIGger:COUPling? /*The query returns LFR*/
:TRIGger:STATus?
Syntax
:TRIGger:STATus?
Description
