Lab #8: Triggering on Unique Pulses and Glitches using “Pulse-width”
Trigger
In this lab you will learn how to use the scope’s Pulse Width triggering mode to
trigger on pulses within a digital data stream that have unique pulse widths,
including an infrequently occurring glitch.
1
Connect the channel-1 probe to the Demo 1 terminal and ground.
2
Press
[Default Setup]
on the scope’s front panel.
3
Press
[Help]
; then press the
Training Signals
softkey.
4
Tap the
Digital Burst with Infrequent Glitch
signal from the
Training Signals
menu.
5
Set channel-1’s vertical scaling to
1.00 V/div
.
6
Set channel-1’s offset/position to approximately
+1.7 V
in center the waveform
on-screen.
7
Set the trigger level to
+1.00 V
(~1 division above bottom of waveform).
8
Set the scope’s timebase to
2.000 µs/div
.
