CDMA Diagnostics
The Digital Diagnostics test the assemblies required for CDMA-formatted IQ
modulation.
These assemblies include:
• CDMA Reference
• LO/IF Demod
• I/Q Modulator
• Cell Site Analog
The CDMA Reference, LO/IF Demod, and I/Q Modulator are also used when
generating or analyzing analog signals.
NOTE
Before ordering a replacement assembly...
Before ordering an assembly based on the results of the diagnostics, you should
verify the diagnostics by other means if possible. This could include using manual
troubleshooting procedures and descriptions of the AF, RF, and CDMA diagnostics
in this chapter, and/or block diagrams in
249. If you still lack confidence in troubleshooting or diagnosing the problem or
faulty assembly, call the Agilent Call Center (1-800-922-8920) for troubleshooting
assistance.
