3 Advanced Triggering, Search & Navigation, and Segmented Acquisition Labs

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

Figure 41. The channel- 1 waveform (yellow trace) is a clock signal, while

the channel- 2 waveform (green trace) represents a random data signal

Figure 41 Display of a clock signal (yellow trace) and data signal (green trace) in the form

of an eye-diagram.
