Chapter 10: Making Coordinated Measurements
Using Trigger Signals
To break emulator execution on signal from BNC
1 Enter the modify configuration command.
2 Answer "yes" to the "Modify interactive measurement specification?" question.
3 Answer "drive" to the "Should BNC drive or receive Trig1?" question.
You could also break emulator execution on a trigger signal from the BNC over the
trig2 internal line by specifying that the BNC should drive trig2 and that the
emulator break should receive trig2.
To break emulator execution on external analyzer
trigger
1 Enter the modify configuration command.
2 Answer "yes" to the "Modify interactive measurement specification?" question.
3 Answer "yes" to the "Should Emulator break receive Trig2?" question.
4 Answer "drive" to the "Should External Analyzer drive or receive Trig2?" question.
When an emulator break occurs due to the analyzer trigger, the analyzer will stop
driving the internal signal that caused the break. Therefore, if trig2 is used both to
break and to drive the CMB TRIGGER (for example), TRIGGER will go true
when the trigger is found and then will go false after the emulator breaks.
However, if trig1 is used to cause the break and trig2 is used to drive the CMB
TRIGGER, TRIGGER will stay true until the trace is halted or until the next trace
starts.
