RM-25
RF troubleshooting
Steps
1. Start Phoenix Service software.
2. Establish connection to the phone.
From the File menu, choose Open Product.
From the list, choose RM-25.
3. From the Testing menu, choose RF Controls.
4. In the RF Controls window:
i Select Band EGSM900.
ii Set Active unit to RX.
iii Set Operation mode to Continuous.
iv Set RX/TX channel to 37.
v Set AGC to 12.
Set the frequency and level of the signal generator to 942.4677MHz and -60dBm.
Note: Because DC compensation does not work during continuous mode, DC offset level at RXI and
RXQ will gradually shift from the optimized level.
To have the most reliable result, it is highly advisable to set the operation mode from burst to
continuous just before measuring values and complete measurement within no longer than 30
seconds.
