9. If the values are within the limits, click "Calculate,Write & Finish". Repeat steps 7 to 9. for each band that

needs tuning.

10. When tuning EDGE with the VSA use 50 averages and 10 averages for non-EDGE.

11. Tune EDGE power levels to the corresponding target power levels.

Only power levels 8, 15 and 19 are tuned in GSM900 and 2, 10 and 15 in GSM1800/1900.

12. When the tuning is completed, close the Tx Power Level Tuning window.

WCDMA receiver tunings

RX calibration (WCDMA)

Context

Rx calibration tuning routine calculates the real gain values of the WCDMA Rx AGC system. There is also a SAW

filter between front end LNA and mixer in the receive chain, which causes ripple in the RSSI measurement,

this is calibrated out. The SAW filter is intergated into RF ASIC N7500.

Rx calibration can be done in two different ways, manual tune and sweep mode tune. If the signal generator

in use supports frequency sweep table, the calibration is done in one step.

Steps

1. For manual tuning, set mode to Local in the Operating Mode dropdown menu.

2. In the Tuning menu, choose WCDMA→Rx Calibration .

3. Click Start.

4. Select Band "WCDMA 2100".

5. Click Tune.
