Functional Verification
This section contains instructions for performing the functional verification
procedures for the logic analyzer. These procedures provide an easy way to check
the basic functionality of the logic analyzer and probes. The test fixture or
software is not required for any of the functional verification checks.
If any check within this section fails, refer to the Troubleshooting section in the
Maintenance chapter of this manual for assistance. Failed tests indicate the
instrument needs to be serviced.
The functional verification procedure consists of the following parts:
H
Self tests and power-on diagnostics
H
Extended diagnostics
H
Mainframe diagnostics
H
Probe functional verification
This procedure provides a functional check only. If more detailed testing is
required, perform the
Performance Verification Procedures beginning on
page 4--11 after completing this procedure.
Perform these tests whenever you need to gain confidence that the instrument is
operating properly.
You will need the following equipment to complete the functional verification
procedure:
H
TLA5000 series logic analyzer
H
At least one logic analyzer probe
H
One short BNC-to-BNC cable (to complete the Mainframe Diagnostics)
Power on the logic analyzer and allow a 30-minute warm-up period before
continuing with any procedures in this section.
During power-on, the instrument performs an internal self test to verify basic
functionality. No external test equipment is required.
Next, the power-on diagnostics are run. If any self tests or power-on diagnostics
fail, the instrument displays the Calibration and Diagnostics property sheet
showing the failed test.
