Understanding Test Failures
This section is intended to be used in conjunction with the Agilent 8922 Series
Assembly Level Repair Guide for assembly level repair and troubleshooting. If a
performance test fails and hardware is suspected, the following table is a guideline
to help identify the hardware assemblies most likely to cause each failure. Before
replacing an assembly, the memory card diagnostics (supplied with the Assembly
Level Repair Guide) should also be run to help verify which assembly is defective.
