TRIGger Subsystem
The TRIGger subsystem { XE “” } is used to define the length of a measurement and how
a measurement is initiated. The values for the TRIGger subsystem are INTernal, external
FALL, or external RISE.
:SEQuence:METHod?
Description
Queries the trigger method being used for data collection.
Query Response
{ INT | FALL | RISE }
Examples
:TRIG:SEQ:METH?
:SEQuence:METHod { INT | FALL | RISE }
Description
Sets the trigger method being used for data collection.
*RST value
INT
Examples
:TRIG:SEQ:METH FALL
:TRIG:SEQ:METH INT
:TRIG:SEQ:METH RISE
:SEQuence:RATE?
Description
Queries the rate of the last set internal trigger used for data collection.
Not all rates are available for a given model. If the
:TRIGger:SEQuence:RATE:ADJust has been used the response will
not reflect the true data acquisition rate.
Query Response
{ 20 | 50 | 100 | 250 | 500 | 1000 }
Examples
:TRIG:SEQ:RATE?
:SEQuence:RATE { 20 | 50 | 100 | 250 | 500 | 1000 }
Description
Sets the rate of the internal trigger used for data collection. The
INTernal TRIGger is specified as the number of measurements per
second.
*RST value
1000
Examples
:TRIG:SEQ:RATE 250
