Lab #11: Triggering on and Searching for Runt Pulses
A “runt” pulse is defined as either a positive or negative digital pulse that fails to
meet a minimum required amplitude. In this lab you will learn how to set up the
scope to trigger on runt pulse conditions. In addition, we will be using the scope’s
Search & Navigation capability to automatically find, mark, and then navigate to
runt pulses, as well as use the scope’s segmented memory acquisition to capture
multiple and consecutive occurrences of runt conditions.
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 tap the

softkey.
4
Select the
Runt Pulses
signal.
5
Set channel-1 to
500 mV/div
.
6
Set channel-1 offset/position to approximately
1.6 V
to center the waveform
on-screen.
7
Push the trigger level knob to automatically set the trigger level to
approximately
50%
.
8
Set the scope’s timebase to
100.0 ns/div
.
