Advanced bridge instrument for the measurement of the phase noise and of the short-term frequency stability of ultra-stable quartz resonators
2007 IEEE International Frequency Control Symposium Joint with the …, 2007•ieeexplore.ieee.org
This article reports on the advances in the characterization of an instrument intended to test
5 MHz and 10 MHz crystal resonators packaged in HC40 enclosure, that used for the high-
stability space resonators. Improvements concern the design of new double ovens, the
reduction of the residual carrier, a lower drift, and a modified calibration process. The
instrument sensitivity, that is, the background phase noise converted into Allan deviation, is
of 10-14.
