Tuning of the RX Using Phoenix
RX Channel Select Filter Calibration
This calibration is calibrating the Baseband filter inside Mjølner ASIC. It is done by internally
measuring a prototype filter, for this reason the calibration is done once, not separately for all
three bands.
• Select Tuning -> RX Channel Select Filter Calibration.
• Press Tune.
RX channel select filter calibration is finished.
RX Calibration
The RX Calibration is used to determine the gain at different gain settings for the front-end and
the Mjølner ASIC and needs to be done in all three bands.
RX-calibration requires an external signal generator.
• Select Tuning -> RX calibration.
• Select band: GSM900.
