Troubleshooting Procedures
Use the following information to isolate problems to the probe or to the logic
analyzer. You can monitor any error messages that display on the logic analyzer
screen.
Slow Clock.
The logic analyzer starts but does not receive a clock from the
probe. If this message displays on the logic analyzer, check for one or more of
the following possible problems:
H
Verify the jumpers on the probes are in the correct positions for your
application. If necessary, refer to Figures 1 through 4 on pages 3 through 6 in
this manual for the jumper settings and locations.
H
Verify that the probe power cable is connected and delivers power to the
probe.
H
Check the fuses on the P6467 Probe.
H
Verify that you have the correct clock selected in the Clock menu for both
acquisition modules.
H
Verify that you have the Trigger menu set up properly for both acquisition
modules.
H
Verify that the flex cables of the probe are correctly connected to the
system-under-test.
H
Verify the threshold voltage is set properly on the probe.
H
Verify that the threshold voltage on both Channel menus is set correctly.
Incorrect Data Acquired.
If the logic analyzer acquires incorrect data, check for
one or more of the following possible problems:
H
Verify that the NORM/DIV2 jumpers are in the correct positions on the
probe.
H
Isolate the problem to a faulty probe by substituting a known good probe
(ensure that you place the jumpers in the correct positions if you replace one
of the probes that acquires the clock signals.
H
Verify the threshold voltage is set properly on the probe.
H
Verify that the threshold voltage on both Channel menus is set correctly.
