摘要：
A high stability oscillator circuit 100 having an output 150 and a multiple of reference oscillators 102, 104, and 106 for enhanced stability and reliability is disclosed. The output signals of these oscillators 108, 110, and 112 are mixed and analyzed for determination of excessive frequency shift including component failure. Additionally a switch 148 decouples the shifted oscillator signal from the output of the circuit 150 and couples another one of the oscillators in its place.
