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 Connect the channel-1 probe to the Demo 1 terminal and ground.
2 Connect the channel-2 probe to the Demo 2 terminal and ground.
3 Press [Default Setup] on the scope’s front panel.
4 Press [Help]; then press the Training Signals softkey.
5 Select the Edge then Edge signal.
6 Set channel- 1 to 1.0 V/div; set the channel- 1 offset to -1.0 V
7 Press the [2] front panel key to turn on channel- 2.
8 Set channel- 2 to 1.0 V/div.
9 Set channel- 2 offset/position to approximately 2.0 V.
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 1.0 µs/div.
