1. A radio frequency generation system comprising:

  • a synchronization board that receives an external clock signal from a clock source and generates multiple copies of the external clock signal;

    a plurality of RF signal generation boards each of which receives a copy of the external clock signal from the synchronization board, wherein each signal generation board comprises;

    a plurality of direct digital synthesizers each having a reference clock input and a synchronization input;

    replicator circuitry that distributes substantially identical copies of the external clock signal to the reference clock inputs of each of said plurality of direct digital synthesizers; and

    translator circuitry that generates a translated version of the external clock signal and distributes the translated version of the external clock signal to the synchronization inputs of each of said plurality of direct digital synthesizers.
