The key to making these measurements stems from the generation of extremely stable reference signals which are synthesized by the combination of an ultra-stable sapphire resonator (oscillator), a set of low-noise regenerative dividers, and a set of cavity-stabilized Gunn oscillators. To date there have been no high-stability reference sources for measurements across this frequency region.
