the stimulus board’s pod 5 connector — just using
different probes.
b Select the Run icon .
If the failure is the same (that is, the error follows the
cable) then the cable is faulty.
If the failure switches pods (that is, the error follows the
E5379A probe) the probe is faulty.
12 Repeat the cable test for pods 3 and 4:
a Connect the logic analyzer’s pod 3 cable to the
stimulus board’s pod 4 connector.
b Connect the logic analyzer’s pod 4 cable to the
stimulus board’s pod 5 connector.
c In the Buses/Signals tab of the Analyzer Setup window,
assign the pod 3 and 4 channels to “My Bus 1”.
d In the Sampling tab of the Analyzer Setup window, for
State Clock, select Both edges.
e Adjust sampling positions.
f Select the Run icon . In the Listing window, check
at least 256 samples for failures; if necessary, verify
any failures by swapping the E5379A probes.
13 Repeat the cable test (step12) for pod pairs 5 and 6 and
7 and 8 connecting the odd pod cable to the stimulus
board’s pod 4 connector and the even pod cable to the
stimulus board’s pod 5 connector:
