PERFORMANCE
The Model
6610 provides precision phase measurements with a typical accuracy of 0.02°
and 0.01° resolution over most of the frequency range. It will accept a wide
range of input signal levels from 10mV to 320V rms and input waveforms 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 ±180.00°. These
two ranges can be manually or automatically selected.
UNIQUE DESIGN
Two common factors will
affect the accuracy of a phasemeter are distortion and/or broadband noise
present on either or both the input signals. A unique circuit design used
in the 6610 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 6610 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.
STANDARD FEATURES
The 6610 provides a RELATIVE
measurement mode which allows the monitoring of phase deviations without having
to make unwanted calculations. Also provided are an automatic selection of
the input voltage range, front panel indictors to indicate a too low/high
input voltage range, and an analog output for use with an external meter or
strip chart recorder.
APPLICATIONS
The 6610 is the ideal
instrument for precision phase angle measurements. Its superior performance
and affordable price, make it the best choice for a broad range of applications
which include monitoring servo control systems, low impedance measurements,
adjustment of crystal resonance, testing and adjustment of filter networks,
controlling laser trimming of resistor networks, measurements in ac power
systems, secondary standard and general testing and measurement.
