Abstract:

The development of two equipments to be used for the measurement of quartz crystal parameters is presented. The characteristics of the Filter Crystal Test Set include a frequency range of 0.8 to 100 mc. and the capability for measurements of the main mode, unwanted modes, and static capacitance. The characteristics of the Standard Crystal Measurement System include a frequency range of 0.8 to 200 mc. and the capability for highly accurate bridgetype measurements of all crystal parameters utilizing the servo-bridge technique Army Electronics Research and Development Agency, Fort Monmouth, N. J. A new method to simplify bridge type measurements on quartz crystal units, by E. Hafner, 8 Nov 1957. Rept E-1220, PB-163 812. In addition, this report discusses the overall crystal measurement problem and the relation of the equipments developed under this contract to this overall problem. The uses and limitations of the equipment as well as the relations between the two types of equipment are discussed.
