PROBLEM?
Problems/Reasons
If the failure is in a spectrum
analyzer test, it is most likely
a problem in the base
spectrum analyzer platform.
If the failure is in an
Option 190 specific test under
the DVB Analyzer Menu or at
859XE Option 190
Recalibration Software, it is
most likely to be an
Option 190 problem in the
card cage.
Diagnostic/Fix Action
Check the list of Option 190 failures
that can look like spectrum analyzer
problems. If none match, follow the
typical 8594Q analyzer troubleshooting
procedure documented in the
8590 Series Analyzers Assembly-Level
Repair Service Guide.
