5.4 Pulse Trigger
The pulse trigger finds specific pulse widths of positive or negative pulses or on pulse
width ranges. If a pulse on the trigger source fulfills the trigger condition, the oscillo-
scope triggers on the trailing slope. For a positive pulse, it triggers on the falling slope,
and for a negative pulse on a rising slope.
1. Select [TYPE] > "PULSE".
2. To set the polarity, press the [SLOPE] key repeatedly.
The selected polarity is shown above the key, and on top of the grid in the display.
3. To set the trigger level, turn the [Level] knob.
4. Select [FILTER].
The filter settings define the pulse direction and length for the pulse trigger:
TIME t, TIME t

, VARIATION
Set the reference pulse length depending on the selected comparison.
The comparison time can be set between 16 ns to 10s. For values up to 1 ms, the res-
olution is 2 ns. and for any value greater than 1 ms the resolution is 1 μs.
The deviation can be set from ±8 ns up to 657.5 μs with a resolution of 8 ns.
