Lab #13: Triggering on a Qualified Burst using “Edge then Edge” Trigger
In this lab you will learn how to use the scope’s “Edge then Edge” trigger
mode. This trigger mode is sometimes referred to as “qualified A then B”
triggering. “Edge then Edge” triggering allows you to qualify triggering on
an edge of any channel, then delay arming of the final trigger condition by
both time and event count of an edge of any channel.
1

6
Set channel- 1 to
1.0 V/div
.
7
Press the
[2]
front panel key to turn on channel- 2.
8
Set channel- 2 to
1.0 V/div
.
9

.
10
Push the trigger level knob to automatically set the trigger level on both
channels to approximately
50%
.
11
Set the scope’s timebase to
