Specifying the J Clock

If you remember from "What’s a State Analyzer" in Feeling Comfortable With Logic Analyzers, the state analyzer samples the data under the control of an external clock which is "synchronous" with your circuit under test. Therefore, you must specify which clock probe you will use for your measurement. In this exercise, you will use the J clock which is accessible through pod 1.

1.Display the State Format Specification menu.

2.Set the J Clock to sample on a negative-going edge. a. Touch the field labeled Clock.
