Description of settings
Upper Trigger Level / Lower Trigger Level
Set the upper and lower voltage thresholds for the runt trigger. The levels define the
minimum and maximum runt amplitudes.
You can also press the LEVEL key to toggle the upper and lower levels, and turn the
wheel to adjust the focused level. If the focus is on a trigger level, pressing the wheel
also toggles the levels.
Remote command:
TRIGger:LEVel<m>:RUNT:UPPer on page 177
TRIGger:LEVel<m>:RUNT:LOWer on page 177
Polarity
Sets the pulse polarity, that is the direction of the first pulse slope. You can trigger on:
Positive going pulses. The width is defined from the rising to the falling edge.
Negative going pulses. The width is defined from the falling to the rising edge.
Both positive and negative going pulses
Remote command:
TRIGger:RUNT:POLarity on page 178
Range
Defines an additional time limit of the runt pulse.
"Any runt" triggers on all runts fulfilling the level condition, without time limitation. The
other comparisons are the same as for the width trigger, see "Range" on page 52.
