	Using a scope or even a logic analyzer you can make the type of
measurement you're talking about.

	However, you should look to your emulator (assuming one is available).
In addition to making the normal state analysis measurements, some emulators
(read HP's emulators) have a class of measurements called "Software 
Performance Measurements".  The type of measurement you're making is
included in that class.

	Statistics on the latency you're measuring can be given as
well so that you can get a feel for the max/min latency as well as the
average and distribution of particular latency measurements.
