:TRIGger:COUPling 
:TRIGger:COUPling <couple> 
:TRIGger:COUPling? 
Select or query the trigger coupling type.   
{AC|DC|LFReject|HFReject} 
  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). 
The query returns AC, DC, LFR, or HFR.   
:TRIGger:COUPling LFReject /*Set the trigger coupling type to low-frequency 
rejection*/ 
:TRIGger:COUPling?                      /*The query returns LFR*/ 
 
 
:TRIGger:STATus? 
Query the current trigger status.   
The query returns TD, WAIT, RUN, AUTO, or STOP.   
 
 
:TRIGger:SWEep 
:TRIGger:SWEep <sweep> 
:TRIGger:SWEep? 
Set or query the trigger mode.   
  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. 
The query returns AUTO, NORM, or SING.   
:TRIGger:SWEep SINGle /*Select single trigger mode */ 
:TRIGger:SWEep?                  /*The query returns SING*/
