Introduction to receiver (RX) troubleshooting

RX can be tested by making a phone call or in local mode. For the local mode testing, use Phoenix service
software.
The main RX troubleshooting measurement is RSSI reading. This test measures the signal strength of the
received signal. For GSM RSSI measurements, see GSM RX chain activation for manual measurements / GSM
RSSI measurement (page 4–18). For a similar test in WCDMA mode, see WCDMA RSSI measurement
(page 4–21).
