INTELLIGENT RF REDUNDANCY SWITCH

摘要

An RF redundancy switch for selecting and outputting an output signal from a plurality of source signals. The RF redundancy switch selects the output signal from the input RF signals based on measurement of at least one signal validity criteria for the plurality of source signals, by application of a signal selection function thereto. The output signal is switched any time that the RF redundancy switch, using the signal selection function, determines that a different source signal should become the output signal. The RF redundancy switch allows a user to set the signal selection function by an interface. A method of intelligent RF redundancy switching between a plurality of RF input signals is also disclosed.

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.
