RIGOL
Example:
:TRIGGER:EDGE:SOURce□CHANnel1 Set the edge trigger source as channel 1.
:TRIGGER:EDGE:SOURce?
3. :TRIGger<mode>:LEVel
Command Format:
:TRIGger<mode>:LEVel□<level>
Function:
The command sets the voltage level of Edge, Pulse or Video trigger. The
<mode> may be :EDGE, :PULSe or :VIDEO or PATTern.
<level> range: (- 6*Scale-Offset①) ~(+6*Scale+Offset①).
Scale is the current vertical scale, and the unit is V/div. If choose PATTern mode,
it needs SOURce parameter.
NOTE①: TtigLevel range is up to+/-6 Scale, when channel has offset, it needs to detract
offset ,such as 1V tap positon, 1V offset, the trigger range is -7V~5V.
Query Format:
:TRIGger<mode>:LEVel?
Return Format:
The query returns the value of voltage level, and the unit is V.
Example:
:TRIGger:EDGE:LEVel□2
:TRIGger:EDGE:LEVel?
4. :TRIGger<mode>:SWEep
Command Format:
:TRIGger<mode>:SWEep□{ AUTO | NORMal |SINGle }
Function:
The command sets the trigger mode.
AUTO (When no trigger is existing, the system will generate a trigger signal to
force trigger.);
NORMal (Acquire waveform when trigger occurred);
SINGle (Execute once trigger when all the condition are marched and stop).
The <mode> may be :EDGE, :PULSe or :PATTern.
2-56
Return CH1.
Set the trigger level as 2V.
Return 2.000e+000.
