Abstract

A software defined radio based phase meter for frequency metrology is presented. By using dual channel digitization, common mode non-idealities of the instrument are minimized. Baseline phase instability of the instrument was measured by using a hydrogen maser 100 MHz output as a reference. Downsampling the phase data from 1 MS/s to 1 S/s reduces the measured noise floor to an Allan deviation of 2·10-14 at an averaging time of 1s in a bandwidth of 0.5 Hz
