I think this RX Calibration method is integrated, and the benefits of solving parameters. According to the SFF8472 protocol, we know that the relationship between MEASUARED RX POWER (RX_PWR (μW)) is: RX_PWR (μW) = RX_PWR (4) * RX_PWRAD4 (16 bit unsigned integer) rx_pwr (3) * RX_PWRAD3 (16 bit unsigned integer) rx_pwr (2) * RX_PWRAD2 (16 bit unsigned integer) rx_pwr (1) * RX_PWRAD (16 bit unsigned integer) Rx_PWR (0)
The process of its test is: 1. Set Starting Power and Ending Power, step by 1DB for Step, stepworks Ending Power, and reads the RAW VALUE inside EEPROM. To this end, two arrays: RX_PWR (μW) and Raw Rx Power, the length of the array is (Starting Power (DB) - Ending Power (DB)) / 1 (dB).
2. A two-dimensional array is generated by Raw Rx Power according to MEASUARED RX POWER (RX_PWR (μW)).
3. Next use General Ls linear fit .vi to solve the proposed 5 factor.
4. The horizontal axis of Front Panel XY Graph is Raw Rx Power, and the vertical axis has two data in the MEASUARED RX Power, the other is the most LS linear Fit.vi, according to the expropriated value and Raw Rx Power calculated one of the most Good RX Power.
5. Write the five coefficients that the General LS linear Fit .vi is written to EEPROM.
