Triggering on a Specific Pulse Width
You are testing the pulse widths of a signal in a circuit. It is critical
that the pulses all be a specific width and you need to verify that they
are. Edge trigge ring shows that your signal is as specified, and the
pulse width measurement does not va ry from the specification.
However, you think there might be a problem.
To set up a test for pulse width aberrations, follow these steps:
1. Display the suspect signal on Ch 1. If Ch1 is not displayed, push
the CH1 MENU button.
2. Push the AUTOSET button to t rigger a stable display.
3. Push the Single Cycle option button i n the AUTOSET Menu to
view a single cycle of the signal, and to quickly take a Pulse
Width measurement.
4. Push the TRIG MENU button.
5. Push the Type option button to select Pulse.
