2.5.4 Width Trigger
The width trigger compares the measured pulse width (duration of a pulse) with a given
time limit. It detects pulses with an exact pulse width, pulses shorter or longer than a
given time, as well as pulses inside or outside the allowable time range. The pulse
width is measured at the trigger level.
Using the width trigger, you can define the pulse width more precisely than with the
glitch trigger. However, using the range settings "Shorter" and "Longer", you can also
trigger on glitches.
Description of settings
Figure 2-3: Width trigger
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:WIDTh:POLarity on page 172
Range
Defines how the measured pulse width is compared with the given limit(s).
