Troubleshooting
TLA721 Benchtop & TLA7XM Expansion Mainframe Service Manual
6- 59
Eliminate other Problem Sources
The TLA700 Series Logic Analyzer comprises modules and the benchtop
mainframes. The following procedures will help you eliminate the mainframe
and other modules as possible sources of the failure.
If you have available a known good controller, perform the following procedure:
1.
Remove the suspect benchtop controller from the mainframe. The benchtop
controller is a slot zero device. First verify that the benchtop controller is
installed in Slot 0 of the mainframe.
2.
Power on the mainframe and check for normal operation.
3.
If the failure symptoms are still present with the known good benchtop
controller installed, the problem is most likely in the benchtop mainframe,
not in the controller.
4.
If your benchtop chassis operates normally with the known good benchtop
controller installed, then the suspect controller is at fault; refer to the
Troubleshoot the Benchtop Controller Module
on page 6--66 for more
information.
If you do not have a known good benchtop controller, perform the following
procedure to make sure the benchtop mainframe is not the source of the failure:
H
Disconnect any attached expansion mainframes.
H
Remove all plug-in modules from the mainframe except the benchtop
controller.
H
Power on the mainframe and check for normal operation. If the instrument
powers on, then the problem is in one of the modules that you removed
earlier, the expansion mainframe, or cables connecting the expansion
mainframe.
Diagnostics
The following diagnostics are available for the logic analyzer. Only those tests
that apply to the mainframe and benchtop controller are listed here. For
information on diagnostics that are run on individual product modules, refer to
the appropriate service manual.
