To configure and calibrate the ADI transceiver cards, follow the steps listed below:
1. At the Linux prompt, enter the command listed below.
#dfe_config.sh –-x0 1 –-x1
0
–t
1
–s 1 –r 0 –i 307 –l 1845
Set the number following
x0
and
x1
as
1
or
0
depending on the availability of the ADI cards on the board.
NOTE
To use a different local oscillator (LO) frequency, change the last number in the
above commands to the desired LO frequency value in MHz.
2. Send the configuration to the hardware using the command listed below.
#dfe_setup.sh
NOTE
In case the transceivers fail to synchronize, run the
dfe_setup.sh
command
again.
3. Run the calibration sequence on the transceiver card using the command listed below.
#xcvr_cal.sh
The ADI transceiver cards are now ready for transmission and adaptation.
