TLA7AXX Logic Analyzer Module Service Manual
During power-on, the installed modules perform an internal self test to verify
basic functionality. No external test equipment is required. The self tests require
only a few seconds per module to complete. The front-panel ARM’D and
TRIG’D indicators blink during the self test. After testing completes, the front
panel indicators have the following states:
H
READY — Green (on)
H
ACCESSED — off
H
ARM’D — off
H
TRIG’D — off
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.
NOTE
. If any diagnostics fail, you may need to run the self calibration before
attempting to service the logic analyzer module. This may be especially true
after you install the logic analyzer module in the mainframe for the first time.
The Self Calibration procedure is listed under
Self Calibration beginning on
page 5--5.
The following procedure checks the basic functionality of the logic analyzer
module. You can perform this procedure with individual modules or with merged
modules. Functional verification consists of running the extended diagnostics.
NOTE
. Running the extended diagnostics invalidates any acquired data. If you
want to save any of the acquired data, do so before running the extended
diagnostics.
Perform the following steps to complete the functional verification procedures:
1. Disconnect any probes connected to the logic analyzer module.
2. In the logic analyzer application, go to the System menu and select
Calibration and Diagnostics.
3. Click the Extended Diagnostics tab.
