Application Examples
8. Push the Cursor
2 option .
9. Turn the multipurpose knob to place the second cursor on the data output
transition.
The Δt readout in the Cursor Menu is the p ropagation delay between the
waveforms.
The readout is valid because the two waveforms have the same
Vertical Scale setting.
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 triggering shows
that your signal is as specified, and the pulse width measurement does not vary
from the specifi cation. However, you think there might be a problem.
To set up a tes t for pulse width aberrations, follow these steps:
1. Push the AutoSet to trigger a stable display.
2. Push the Single Cycle option in the Autoset Menu to view a single cycle of
the signal, and to quickly take a Pulse Width measurement.
3. Push the Trig Menu to see the Trigger Menu.
4. Push Type ► Pulse.
5. Push Source ► CH1.
6. Tu
rn the Trigger Level knob to set the trigger level near the bottom of the
signal.
7. Pu
sh When ► = (equals).
8. Turn the multipurpose knob to set the pulse width to the value reported by the
P
ulse Width measurement in step 2.
9. Push More ► Mode ► Normal.
You can achieve a stable display with the oscilloscope triggering on normal
pulses:
