Rx band filter response compensation
Before you begin
Rx calibration must be performed before the Rx Band Filter Response Compensation
Context
In each GSM Rx band, there’s a band rejecting filter in front of the HINKU 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 module jig’s GSM connector to the signal generator.
2.
From the dropdown menus, set "Operating mode" to "Local" and Band to "GSM900".
