HP 1660 Series User Manual

To test the threshold accuracy (logic analyzer)
Testing the t hreshold 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 the voltage reading in the performance test
record located at the end of this chapter. To check if each test passed, verify that
the voltage reading you record is within the limits listed on the performance test
record.
