Lab #9: Triggering on the Nth Pulse within a Burst using “Nth Edge Burst”

Trigger

In this lab you will learn how to use the scope’s “Nth Edge Burst”

triggering mode to trigger on pulses within a burst based on pulse count.

Note that we will be using the same training signal that we used in the

previous lab.

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 Open the Training Signals: Sine menu and double- tap the Digital Burst with

Infrequent Glitch signal.

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 500 ns/div.
