TLA Mainframe diagnostics
On power up, the instrument automatically runs the power on BIOS test. If the
power on BIOS test detects a problem, BIOS error(s) will be displayed. The
BIOS error messages are found in Table 6--12 on page 6--62.
The power-on diagnostics check the basic functionality of the instrument at every
power on. If any failures occur at power on, the screen displays the calibration
and diagnostics property page. Table 6--11 lists a subset of the power on tests.
Use the results of the tests to help you isolate problems. You can also select the
Calibration and Diagnostics property page from the System menu of the logic
analyzer application.
The power on tests ensure that hardware is installed and can be accessed by the
software. The tests do not provide any performance information, but they
provide limited diagnostic information. The TLA Mainframe diagnostics provide
more extensive tests than the power-on diagnostics. The interrupt lines and
trigger lines are tested for each installed application module.

The extended diagnostics provide more in-depth information than the power-on
diagnostics. The extended diagnostics test modules in the mainframe and in the
expansion mainframe. You can use the extended diagnostics to isolate problems
to a single module or to a mainframe. To display the extended diagnostics, select
the Extended tab in the Calibration and Diagnostics property page. Disconnect
probes attached to module before starting the diagnostics.
