Lab #10: Triggering on and Searching for Edge Speed Violations
In this lab you will learn how to set up the scope to trigger on edge speed
violation conditions using the scope’s “Rise/Fall Time” trigger mode. We
will also be using the scope’s Search & Navigation capability to
automatically find, mark, and then navigate to edge speed violations, as
well as using the scope’s Segmented Memory acquisition to capture
multiple and consecutive occurrences of edge speed violations.
1
Connect the channel- 1 probe to the Demo 1 terminal and ground.
2
Press
[Default Setup]
on the scope’s front panel.

Press
[Help]
; then press the

softkey.
4
Using the Entry knob, select the
Edge Transition Violation Signal
; then press
the
Output
softkey to turn it on.
5
Set channel- 1 to
500 mV/div
.
6
Set channel- 1 offset/position to approximately
1.6 V
to center the
waveform on- screen.
7
Push the trigger level knob to automatically set the trigger level to
approximately
50%
.
8
