Lab #8: Triggering on Unique Pulses and Glitches using “Pulse-width”
Trigger
In this lab you will learn how to use the scope’s Pulse Width triggering
mode to trigger on pulses within a digital data stream that have unique
pulse widths, including an infrequently occurring glitch.
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 Tap the Digital Burst with Infrequent Glitch signal from the Training Signals
menu.
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 2.000 µs/div.
