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.
