To Test The Threshold Accuracy (Logic Analyzer); Set Up The Equipment - Agilent Technologies 1670G Series Service Manual

To test the threshold accuracy (logic analyzer)

Testing the threshold accuracy verifies the performance of the following specification:
•
Clock and data channel threshold accuracy.
These instructions include detailed steps for testing the threshold settings of pod 1.
After testing pod 1, connect and test the rest of the pods one at a time. To test the
next pod, follow the detailed steps for pod 1, substituting the next pod for pod 1 in
the instructions.
Each threshold test tells you to record a pass/fail reading in the performance test
record located at the end of this chapter.
