Abstract :
The environmental sensitivity of key elements of measurement systems, frequency synthesizers, and frequency distribution systems designed to achieve frequency stabilities on the order of σy (τ)=5×10-15 τ-1/2 in the short-term and 3×10-18 in the long term is examined. The timing errors in signal transmission for distances up to 100 m and the effect of changes in temperature and RF amplitude on timing (or frequency) errors in several available phase detectors operated in different configurations are investigated
