Isolating Out-of-Lock Conditions
If more than one OOL indicator is lit.
CDMA Reference and LO/IF Demod: If the CDMA Reference is unlocked, the
LO/IF Demod assembly will be unlocked, since its reference comes from the
CDMA Reference. Verify that the CDMA Reference (A29) is working correctly
before troubleshooting the LO/IF Demod assembly.
Receiver Synthesizer and Signal Generator Synthesizer: If both assemblies are
unlocked, the Reference (A27) is the probable cause, since it provides the
reference for both assemblies.
