:TRIGger:COUPling
Syntax
:TRIGger:COUPling <couple>
:TRIGger:COUPling?
Description
Select or query the trigger coupling type.
Parameter

Type
Range
Default
<couple>
Discrete
{AC|DC|LFReject|HFReject}
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
Query the current trigger status.
Return
Format
The query returns TD, WAIT, RUN, AUTO, or STOP.
:TRIGger:SWEep
Syntax
:TRIGger:SWEep <sweep>
:TRIGger:SWEep?
Description
Set or query the trigger mode.
Parameter
Name
Type
Range
Default
<sweep>
Discrete
{AUTO|NORMal|SINGle}
AUTO
Explanation
 AUTO: auto trigger. No matter whether the trigger condition is met, there is always
waveform display.
 NORMal: normal trigger. Display waveform when the trigger condition is met;
otherwise, the oscilloscope holds the original waveform and waits for the next trigger.
 SINGle: single trigger. The oscilloscope waits for a trigger and displays the waveform
when the trigger condition is met and then stops.
Return
Format
The query returns AUTO, NORM, or SING.
Example
:TRIGger:SWEep SINGle /*Select single trigger mode */
:TRIGger:SWEep? /*The query returns SING*/
