5 Troubleshooting
To test the logic acquisition cables
This test allows you to functionally verify the logic analyzer
cable and the flying lead probe of any of the logic analyzer
pods. Only one probe and cable can be tested at a time.
Repeat this test for each probe and cable to be tested. Two
Flying Lead Probes are required if you need to test pods
other than Pod 1 because the clock from Pod 1 will be used
to acquire data.
To assemble the 2 x 9 test connectors
The 2 x 9 test connectors are used to connect all 16
channels and the clock of the logic analyzer to the pulse
generator so you can test the flying lead probe and cables.
(See “To test the logic acquisition cables" on page 98.)
