Repeat steps to for GSM and GSM Rx band filter response compensation GSM Before you begin

Rx calibration must be performed before the Rx band filter response compensation. Context

On each GSM Rx band, there is a band filter in front of the RF ASIC front end. The amplitude ripple caused by these filters causes ripple to the RSSI measurement, and therefore calibration is needed.

The calibration has to be repeated for each GSM band. Steps

1. Connect the GSM connector of the module jig to a signal generator.

2. Start Phoenixservice software.

3. From the Operating mode drop-down menu, set mode to Local.

4. Select GSM900 band.

5. Choose Tuning^GSM^Rx Band Filter Response Compensation .

6. Select Tuning mode: manual

7. Click Start.

8. Connect the signal generator to the phone, and set frequency and amplitude as instructed in the Rx Band Filter Response Compensation for EGSM900 pop-up window, step 1-3.
