Claim:
1. An RF redundancy switch for outputting a selected output signal selected from a plurality of source signals, said RF redundancy switch comprising: a plurality of signal inputs, each for receiving a source signal from an RF signal generator; a signal output for outputting an output signal, being a selected source signal corresponding to one of the signal inputs; a signal switch operatively connected to the plurality of signal inputs and the signal output, to select and output a selected one of the plurality of source signals on the signal output as the output signal; a signal monitor capable of continuously monitoring the plurality of signal inputs and capturing at least one signal validity criteria for each source signal; and a signal comparator in communication with the signal monitor which uses a signal selection function to select the output signal, based on the at least one signal validity criteria captured by the signal monitor; wherein in operation of the RF redundancy switch, the signal switch switches the output signal sent to the signal output each time a new output signal is selected by the signal comparator; and wherein the RF redundancy switch allows a user to select the signal selection function to be used by the signal comparator.
