    1313The calibration algorithm is not publically available. However, we do distribute an FPGA configuration file which executes the calibration process automatically.

    15  1) Download a copy configuraiton file - TxDCO_Calibrate.bit
    16  1) Use the DIP switch on the WARP FPGA Board to select which radios should be calibrated. Each switch position corresponds to a radio. The LSB (Radio #1) is the bottom switch; MSB (Radio #4) is the top.
    17  1) Connect a serial cable to the FPGA board and set your terminal emulator to 57600bps
    18  1) Power on the FPGA board and wait for a few minutes; this allows components to warm up
    19  1) Configure the FPGA using TxDCO_Calibrate.bit
    20  1) The terminal will display the status as it runs. Wait for the calibration of each radio to complete.

    2222You can repeat this process whenever needed. In our experience, calibration values are fairly static over time but do vary with temperature.
