DESCRIPTION
The Model 6600 provides
precision phase measurements with a typical accuracy of 0.1° and 0.1° resolution
over most of the frequency range. It will accept a wide range of input signal
levels from 10mV rms to 320V rms and input waveforms including sine, triangle,
square and pulses. A 4 digit, LED display provides continuous direct readout
of phase angles between 0.0° and 360.0°.
APPLICATIONS
The 6600 is the answer for precision
phase angle measurements. Its superior performance and low price, make it ideally
suited 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.
UNIQUE DESIGN
Two common
factors 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 6600 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 6600 uses
a design that eliminates any ambiguities that may occur at readings near 0°,
180° and 360°.
STANDARD FEATURES
Provided
are an automatic selection of the input voltage range, front panel indicators
to indicate a too low/high input voltage range, and an analog output for use
with an external meter or strip chart recorder.
