Description of vibration equipment and PM noise measurement. Primary Measurement Effects due to Motion of an Ideal Device Under Test (DUT): Path fluctuation Uniform motion OUTLINE OF TALK Relativity under vibration Cable multipath instability and impedance mismatch Calculation of Γ = 1/2 per g Measurements of PM noise of a low-vibe-sensitivity Qz under vibration: Sine-wave vibration, 20 – 2000 Hz Random-noise vibration, 10 – 200 Hz Scatter plots of phase-fluctuations vs. acceleration Strategy for constructing ultra-low noise microwave reference oscillator with reduced acceleration sensitivity.
