Rf Self Tests - Nokia 6680 RM-36 Service Manual

Appendix A: RF Troubleshooting Nokia Customer Care

2. RF SELF TESTS

The RF part of the device is equipped with self test functionality which tests most of RF-BB interface
signals and some parts of RF circuitry. Self tests are designed to detect faults on some critical parts,
but they can not prove that everything is OK even if all the self tests are passed.
Self-tests can be run with Phoenix service software. Tests can return pass/fail result and detailed
measurement data and error codes in fail case. Select "Testing" -> "Self Tests" from the Phoenix menu.
Select appropriate RF self tests and run them with "Start"-button. Notice that self tests should be run
in "Local"-mode (change "Operating Mode" to "Local" in Phoenix before running self tests). For service
tool usage instructions refer to the "Service Software" and "Service Tools and Service Concepts"
sections.
NOTICE! Perform WCDMA transmitter self test (ST_CDSP_WCDMA_TX_POWER_TEST) always in an RF
shielded environment (for example in an RF-shield box).
