A method for operating a microwave threshold device to increase threshold stability in the presence of component drift comprising the steps of:
- locating the threshold device along a microwave signal transmission line at a point developing large signal electric field and tight signal to threshold device coupling;
- priming the threshold device with a level of microwave energy sufficient to reduce the transmission line signal needed to reach said threashold;
- coupling said priming energy to said threshold device through a microwave resonator;
- controlling the frequency of said priming energy with the same resonator used to couple said priming energy to said threshold device.
