Abstract :
We report on the latest cryogenic sapphire oscillator the developed at the University of Western Australia and the use of two nominally identical cryogenic oscillators to evaluate frequency synthesis configurations using a down converter. The down converter is used to make comparisons between microwave clocks at different frequencies, where the synthesized signal has a stability not significantly different from the reference oscillator.
