-The RF clocking uses the thick, black RF cables with MMCX connectors at either end. This clock feeds the radio and allows it to tune to a user-programmable center frequency. This figure at the right shows the visual representation of how the RF clocking cables should be connected from radio boards to the clock board. The following table provides the details.

+The cables used for the sampling clock are the green and white twisted pair cables that are roughly 3.25 inches long. These clock the ADCs and the DACs on the radio, and their orientation is important. The figure at the right shows the visual representation of how they should be connected.
