Experimental procedure applied to characterize crystal oscillator under functional environment

Abstract

The methods used by CEPE in following areas are presented: g sensibility dynamic test (spectrum analysis of phase fluctuation under known random vibrations); acoustic sensitivity (spectrum analysis of phase fluctuation under known acoustic excitation); power supply sensitivity (spectrum analysis of phase fluctuation with ripple on power supply); barometric (pressure) sensitivity; and magnetic field sensitivity. Description of test equipments and procedures of these various measurements are given. Typical results (including reproducibility) are presented.<>
