The following are the available Mac Error functions:
1. Get – The Current and Last Mac Error are queried from the reader. Diagnostic codes are
also queried and displayed
2. Clear – The Clear Mac Command is executed. Note that the Last Mac Error register is not
clearable, only the current Mac Error will be cleared.
Calibration
The Calibration menu is shown in the following figure.
The following are the available Calibration functions:
1. OEM Strings – Read and Write the OEM Strings directly. The available strings are
Manufacturer, Product and Serial.
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 is
generated can be used in the future to configure the same reader with the same calibration
data.
