Abstract : Work was performed to achieve two major objectives: (1) develop ovenless quartz crystal oscillators having frequency stabilities heretofore obtainable only with oven controlled oscillators over wide temperature ranges; and (2) find methods for standardizing both the oscillator configuration and the methods of obtaining the component values required for compensation. In attempting to achieve the desired stability characteristics, problems were encountered with component tolerances, crystal characteristics, crystal measurement irregularities, and compensation network component selection. A method of standardizing component value selection by computer methods was tried and, within the limitations of the computer used, proved to be quite successful. The three groups of TCXO's were fabricated and tested and found to meet or approach design goal requirements.
