2. RF – The following automatic RF calibration procedures can be performed. Also, the check

box for Write to OEM will automatically store the calibration data to the proper OEM area on

successful calibration completion.

a. Gross Gain Calibration – Requires forward power detector to be calibrated.

b. DC Offset –Requires forward power detector to be calibrated.

c. LBT_RSSI_Threshold – Requires a known signal level (typically -74dBm for Japan) to

be injected into the receive port at the test frequency.

d. PA Bias DAC Value – Does not have any prerequisites.

e. PA Bias Current Coefficients – Does not have any prerequisites.

3. Calibration Data – Dumps RF related calibration data from the OEM configuration

space and

formats the data into an IndyTool Batch Script for future use. The script that

generated

can be used in the future to configure the same reader with the same calibration data.
