Anew precision phase meter is described. The basic 20-c/s to 100-kc/s unit covers a1-mV to 3-V range. This combines with a 1.5- to 45-Mc/s unit which operates between 300 µV and 30 mV without adjustment. Any reference phase may be set to zero with an internal 360° phase shifter. Phase may be read from an internal meter or from a calibrated divider, but for a digital voltmeter, or for sweep measurements, an X-Y recorder may be used. Absolute accuracy is 0.5°.
