PERFORMANCE The Model 6620A provides precision phase measurements with a typical accuracy of 0.02° and a resolution of 0.01° over most of the frequency range. It will accept a wide range of input signal levels from 10mVrms to 320V rms and input waveforms including sine, square and pulses. A 5 digit LED display provides continuous direct readout of phase angles between 0.00° and 360.00° or ±180°. These two ranges can be manually or automatically selected. UNIQUE DESIGN Two common factors that will affect the accuracy of a phasemeter are distortion and/or broadband noise present on either or both of the input signals. A unique circuit design used in the 6620A significantly reduces any effects that may be caused by these two factors. Another problem found in most phasemeters is the inability to respond to very small phase angles, resulting in fluctuations or inconsistencies in the meter reading (sometimes referred to as ambiguity). To overcome this problem, the 6620A uses a design that eliminates any ambiguities that may occur at readings near 0°, 180° and 360°, and allows measurements as small as 0.01° to be made
