Realization of a Phase Reference System Based on Two Synchronized Pulse-Driven Josephson Voltage Standards

In this paper we describe a phase generating system based on two Josephson voltage standards which can be the basis for phase calibrations in the future. Phase measurements are important e.g. in the measurement of electrical power, acoustic signals and dynamic measurements of mechanical quantities (such as force, torque, and pressure). The phase generating system was tested at signal frequencies of 1 kHz, 10 kHz and 100 kHz using two different measurement devices. The measurements were carried out with amplitude ratios in the range of 1:1 to 1000:1 using 100 mV signal amplitude as reference signal.
