Troubleshooting
Functional Diagnostics
RF Modules
The Average and TX power meters, Channel Power Meter, RF analyzer, IF
analyzer and spectrum analyzer are used to test the signal generator. Both the
internal and external paths of the RF/IO assembly are used in the tests.
Analog Modulation
The demodulator in the RF analyzer, and the spectrum analyzer are used to check
the accuracy, distortion, and residuals of the FM and AM frequencies. The counter
is used to measure the audio frequency.
CDMA Loopback
CDMA Analyzer is used to measure Test Mode Rho on a signal from the CDMA
Generator. This test is only a rough indicator of CDMA functionality.
Self Test
The power-up Self-Test Diagnostics are run. Refer to "Self-Test Diagnostics" on
page 48.
Power Supplies
The different levels of the power supply are measured with the internal voltmeter.
