Acquisition/Backplane Assembly Troubleshooting

Acquisition/Backplane Assembly Troubleshooting
This section describes which board assembly to replace if any of the scope self tests
fail. When the self- test error message file is generated it is sent to the following location:
C:\ProgramData\Agilent\Infiniium\selftest\selftestlog.txt
The error message usually indicates the channel with the error. Channels 1 and 2 are
on the lower acquisition board. Channels 3 and 4 are on the upper acquisition board.
Replace the acquisition assembly that has the error.
If the error message does not indicate a channel, refer to the following table to determine
which assembly to replace.
