Receiver troubleshooting

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
RSSI measurement (page
manual measurement / WCDMA RSSI measurement (page
GSM RX chain activation for manual measurements/GSM RSSI measurement

Steps
1. Set the phone to local mode.
2. Activate RSSI reading in Phoenix (Testing→GSM→RSSI reading )
Results

When varying the level in the range -30 to -102 dBm the reading should then follow within +/-5 dB.
