Chapter 5: Troubleshooting
Scroll down at least 256 states to verify the data. Label1 shows two decrementing
binary counters. If the listing does not look similar to the figure, then there is a
possible problem with the cable or high density probe adapter. Cause for cable
test failures include:
• open channel
• channel shorted to a neighboring channel
• channel shorted to either ground or a supply voltage
If the test data is not correct, then perform the following step to isolate the
failure.
9 Verify the failure
a Reconnect probe adapter to the other logic analyzer cable.
b Repeat step 6 through 8 to reconfigure the Format tab in the Setup and
Trigger window. Deactivate the pod just tested. Activate the pod to be
tested and assign all channels to Label1.
c On the logic analyzer, select Run. The expected test data is the same as
in step 8 above.
If the test data is now correct (that is, the error follows the cable) then the cable
is suspect.
If the test data is still not correct (that is, the error follows the E5379A probe
adapter) the probe adapter is suspect.
