Comparison of ultra-stable radio frequency signals synthesized from independent secondary microwave frequency standards
John G. Hartnett, Stephen R. Parker, Eugene N. Ivanov +3
The phase noise and frequency stability measurements of 1 GHz, 100 MHz, and 10 MHz signals are presented which have been synthesized from microwave cryogenic sapphire oscillators u…
A transposed frequency technique for phase noise and frequency stability measurements
John G. Hartnett, Travis Povey, Stephen Parker +1
The digital signal processing has greatly simplified the process of phase noise measurements, especially in oscillators, but its applications are largely confined to the frequencie…
Cavity Bounds on Higher-Order Lorentz-Violating Coefficients
Stephen R. Parker, Matthew Mewes, Michael E. Tobar +1
We determine the sensitivity of a modern Michelson-Morley resonant-cavity experiment to the higher-order nonbirefringent and nondispersive coefficients of the Lorentz-violating Sta…
