Making a Timing Analyzer Measurement
This program sets up the logic analyzer to make a simple timing analyzer
measurement. This example can be used with E2422-60004 Logic Analyzer
Training board to acquire and display the output of the ripple counter. It can
also be modified to make any timing analyzer measurement.
