TRIGger Subsystem
Key access:
166
The TRIGger subsystem is used to set the controls and parameters
associated with triggering the data acquisitions. Other
trigger-related commands are found in the INITiate and ABORt
subsystems.
External Trigger Slope
:TRIGger[:SEQuence]:EXTernal[1]:SLOPe POSitive|NEGa-
tive
:TRIGger[:SEQuence]:EXTernal[1]:SLOPe?
This command activates the trigger condition that allows the next
sweep to start when the external voltage (connected to EXT TRIG
IN on the rear panel) passes through approximately 1.5 volts. The
external trigger signal must be a 0 V to +5 V TTL signal. This
function only controls the trigger polarity (for positive or
negative-going signals).

Set Trigger Offset
:TRIGger[:SEQuence]:OFFSet <time>
:TRIGger[:SEQuence]:OFFSet?
This command sets the trigger offset.
*RST: 0 seconds
Example:
:TRIG:SEQ:OFFS 1.0s
Range: Hardware specific; dependent upon the ADC being used, current
state, and the number of sweep points.
Remarks: Trigger offset refers to the specified time interval before or after the
trigger event from which data is to be written to the trace, and then
displayed. Ordinarily, the trigger offset value is zero, and trace data
is displayed beginning at the trigger event. A negative trigger
