Chapter 4: 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. When identifying which

acquisition assembly to replace, remember that the acquisition assembly nearest the

bottom of the oscilloscope is for channel 1. The one above it is for channel 2. The next

higher is for channel 3, and the top acquisition assembly is for channel 4. 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.

scope and replace backplane

assembly.

Merwig2, Merwig3 Replace acquisition assembly 2.

If error still occurs, put original

acquisition assembly back into

scope and replace backplane

assembly.

Hedwig10, Hedwig11, Oak4

Replace acquisition assembly 3.

If error still occurs, put original

acquisition assembly back into

scope and replace backplane

assembly.
