USER FRIENDLY
Only single keystrokes on clearly labeled keys are required to enter all of the parameters
into the Model 5500-2 Phase Standard. A large bright display shows Phase, Frequency and
both output Amplitudes at all times.
EXTREMELY VERSATILE
The combination of excellent phase accuracy, excellent amplitude accuracy and low
distortion from each channel make the Model 5500-2 Phase Standard ideal for calibrating
Phase Meters, Vector Voltmeters, Broadband Wattmeters and Power Analyzers, Resolvers and
other Phase Sensitive Instruments.
CONTINUOUS PHASE CALIBRATION
The Model 5500-2 Phase Standard contains an Autozero function which measures the output
phase at ±90° and makes an internal correction to remove
any phase errors between the two output channels. The Autozero operation, which takes less
than 0.25 sec., is activated automatically each time an amplitude or frequency is changed.
It may also be activated manually.
DIGITAL PRECISION
Both output sinewaves are generated digitally with the result that the basic parameters of
Phase and Frequency require no adjustments to maintain their superior accuracy. Only the
output amplitudes are adjustable.
LOAD IMMUNITY
The extremely low output impedance of the Model 5500-2 Phase Standard coupled with its
ability to Autozero with an external load in place, makes the phase accuracy of the
instrument completely insensitive to loading.
EXTENSIVE SELF TEST
The Model 5500-2 Phase Standard has an internal SELF TEST capability which checks the
output frequency for all frequency ranges, checks all of the digital sine wave generation
circuitry, checks the output levels of all amplitude ranges for both channels and checks
the Autozero function. If an error is found it is reported in a fashion that leads to
quick repair and restoration of the instrument to service.
EASY TO CALIBRATE
The complete set of specifications of the Model 5500-2 Phase Standard may be checked with
an accurate ac/dc (true rms) Multimeter, an accurate Frequency counter, a good Distortion
Analyzer and the Clarke-Hess Model 5002 Phase Verification Bridge Set. This completely
passive bridge set may be sent either to Clarke-Hess or directly to NIST for annual
recertification.
AUTOMATED ADJUSTMENTS
Many of the adjustments for the internal potentiometers in the Model 5500-2 Phase Standard
are included in an internal calibration routine. If adjustment is required during annual
recertification, the operator just turns the "pot" until a value indicated on
the display is obtained. The ability to operate the instrument over the IEEE-488 interface
makes other adjustments equally straight forward.
