Lab #12: Triggering on Setup & Hold Time Violations
In this lab we will set up the scope to trigger on a Setup & Hold time violation. We
will also use the scope’s Segmented Memory acquisition to capture multiple and
consecutive occurrences of Setup & Hold time violations.
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 tap the
Training Signals
softkey.
5
Using the Entry knob, select the
Setup & Hold Violation Signals
signal; then press
the
Output
softkey to turn it on.
6
Press
[Auto Scale]
, which should set each signal to 1.00V/ and timescale to
50.00ns/.
You should now see on your scope’s display waveforms similar to

channel-1 waveform (yellow trace) is a clock signal, while the channel-2 waveform
(green trace) represents a random data signal presented in an eye-diagram
format. When clocking data into a memory device, if the data signal is going to
