AF, RF, & CDMA Diagnostics (Step 3)
RF Diagnostics
This program tests the RF functions of the following assemblies:
• A2A115 Downconverter
• A2A24 RF Output
• A2A25 Signal Generator Synthesizer
• A2A23 Reference
• A2A21 Receiver
• A2A22 Receiver Synthesizer
• A2A20 Spectrum Analyzer
• A2A130 RF I/O
• A2A110 Upconverter
Some tests require cabling before the RF Diagnostics can be run; but all
tests can be run in a loop mode without further intervention. Running
in loop mode makes it easier to catch intermittent failures. To run these
diagnostics, see
“RF Diagnostics” on page 70 .
NOTE
A fifteen minute warm up is required. The measurement limits of the
SERVICE4 diagnostic tests are valid only at room temperature; that is,
20º to 25ºC (65º to 75ºF).
