Chapter 3: Introduction to Timing Analysis: Trigger on an Edge

Define Trigger Conditions: Trigger on an Edge

A term that should be familiar to oscilloscope users is “triggering”. It is

also used in logic analyzers, and is often called “trace point”. Unlike an

oscilloscope, which starts the trace right after the trigger, a logic

analyzer can show information prior to the trace point, which is known

as negative time, as well as information after the trace point.

You can trigger the analyzer using specified events and edges. In this

exercise, you will use the rising edge of bit 7.

1 Select the Trigger tab.

2 Under the Trigger Functions tab, click on ‘Find edge’.

Trigger functions are predefined trigger sequences that can be

used “as is” or that can be combined and modified for creating

more complex trigger sequences.
