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 Using the Entry knob, select the Digital Burst with Infrequent Glitch signal;
then press the Output softkey to turn it on.
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.
You should now see on your scope’s display a digital burst waveform
consisting of six pulses of various widths, followed by an infrequent glitch
similar to Figure 29. Using the scope’s default Edge triggering mode, the
