Introduction to State Analysis: Trigger on an

Event

If you’ve never used a state analyzer, you may think it’s a complex

instrument that would take much time to master. Actually, the state

analyzer is not any more difficult to understand than a timing analyzer.

The major difference between a timing analyzer and a state analyzer is

the source of the sample clock. While the timing analyzer samples at

regular intervals using the internal clock, the state analyzer samples

when you tell it to using an external clock. Each time the state analyzer

receives a state clock pulse, the analyzer samples and stores the logic

state of the system under test.
