nrf9160 is there an RF calibration parameter at the factory? 2. If there are calibration parameters, does burning mfw_nrf9160_1.2.0.zip firmware affect the calibration parameters? 3. Will the burning at_client.hex application affect the RF calibration

1.nrf9160 is there an RF calibration parameter at the factory?

2. If there are calibration parameters, does burning mfw_nrf9160_1.2.0.zip firmware affect the calibration parameters?

3. Will the burning at_client.hex application affect the RF calibration parameters?

Yes, the nRF9160 is calibrated and the factory and no, you can't affect it in any way with your firmware.
