Abstract :
Several specialized items of equipment have been developed for measuring Allan deviation and power spectral density of phase and amplitude on a variety of equipment types, covering frequency ranges to 10 GHz. These include improved zero crossing detector and offset generator electronics, low noise mixers and frequency multipliers used for frequency translation, high stability bandpass filters, temperature control methods, and a fiber optics signal transportation link to the data processing computer that is immune to spurious signal contamination. The design and use of these items, along with measurement data, are presented
