TLA7AXX/TLA7NAX Logic Analyzer Module Service Manual
You will need the following equipment to complete the functional verification
procedure:
H
TLA700 Series logic analyzer mainframe with one logic analyzer module
installed (more modules are required to check the merged functionality)
H
At least one logic analyzer probe
It is assumed that the logic analyzer module is properly installed in the main-
frame. Refer to
Module Installation on page 2--2 for module installation
instructions.
Power on the logic analyzer mainframe and allow a 30-minute warm-up period
before continuing with any procedures in this section.
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--1.
