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 w*eforms
including sine, triangle, square and pulses. A 5 digit LED display
provides continuous direct readout of phase angles between 0.00°
and 360.00° or &plu*n;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 prese*n either or both of
the input signals. A unique circui*sign 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 *all phase angles, resulting in fluctuati* or
inc*istencies in the meter re*g (sometimes referred to as
ambiguity). To overcome this problem, the 6620A uses a design
that eliminates any ambiguities that may occur at re*gs near 0°,
180° and 360°, and allow*easurements as *all as 0.01° to be
made
