Usage
:TRIGger:EXTernal:OUT:LOGic <logicType>
:TRIGger:EXTernal:OUT:LOGic?
<logicType>
The output logic of the trigger generator:
• Assert a TTL-high pulse for output: POSitive
• Assert a TTL-low pulse for output:
NEGative
Details
This command sets the trigger event generator to assert a TTL pulse for output logic. Positive is a
high pulse; negative is a low pulse.
Example
*RST
:TRIG:EXT:IN:CLE
:TRIG:EXT:OUT:LOG NEG
:TRIG:EXT:OUT:STIM EXT
:TRIG:EXT:IN:EDGE FALL
Reset the external I/O port values to their
defaults.
Clear any event triggers on the external in
line.
Set the output logic to negative (it asserts a
low pulse).
Set the stimulus to the external input.
Set the external input to detect a falling
edge.
