The Model 2335A Wideband Power Analyzer is a precision, high accuracy, high frequency auto-ranging instrument which measures and displays true rms Voltage, true rms Current, and true mean Power over a frequency range from dc to more than 1MHz. Full scale Current and Voltage inputs are typically measured within ?.1% of the amplitude reading to at least 500kHz. The corresponding Power is typically measured to within ?.1% of the input Volt-Amperes to 250kHz and to within ?.2% of the input Volt-Amperes to 500kHz for loads having any Power Factor. MULTI-FUNCTION
In addition to the primary functions, the Model 2335A measures the input Frequency, the phase angle between the current and voltage inputs, and the harmonic amplitudes and phases relative to the fundamental phase, up to 50, for both the current and voltage inputs. It also calculates the Power Factor, the Volt-Amperes, and the Energy (if it has been selected). These functions may be displayed or read over the IEEE-488 or USB interface.
Five digits or resolution combined with excellent phase matching between the current and voltage channels make the Model 2335A an exceptionally good instrument for making low power factor measurements up to 1MHz. This ability makes the instrument ideal for high frequency core loss measurements which have inherently low power factors.
The Model 2335A allows broadband and high accuracy measurements of both sinusoidal and highly distorted wave shapes. The Current, Voltage, Power, and Power Factor uncertainties to 1MHz are far better than any other Watt Meter or Power Analyzer, or for that matter, with respect to Current or Voltage, almost all conventional multimeters.
The Model 2335A has full scale Power ranges from 1.0000mW to 10000W. With external shunts or current to voltage transducers, the upper range may be extended by a factor of ten or one hundred. Full scale Voltage from 2.000V to 2000V (usable to 1000V) and full scale Current ranges from 5.000mA to 5.000A (all rms values) cover a wide range of load impedances. Full scale Current and Voltage inputs may have crest factors up to three while smaller inputs may have even higher crest factors. Sinusoidal inputs with rms values of twice the nominal Full Scale value may be measured with no loss in accuracy.POSSIBLE MEASUREMENT USES
The Voltage and Current inputs of the Model 2335A are simultaneously sampled (with 16 bit resolution), converted to digital form, and transmitted via isolated links to the control board on the main chassis. This allows both the Current and Voltage inputs to be compley isolated from each other and from the main chassis ground. The asynchronous sampling frequency is controlled by the system microprocessor in such a fashion that neither it nor any of its harmonics can come close to the measured input frequency or any of its harmonics. This precaution permits sampling at frequencies that are significantly below the Nyquist rate.
The Model 2335A is equipped with an IEEE-488.2 interface and a USB interface which both incorporate all of the IEEE-488.2 Common Commands and Queries as well as the commands and queries required for device operation. Any function that can be entered via the front panel can be controlled via either interface. A menu item selects either the IEEE-488 or the USB interface to be active.

The Total Harmonic Distortion accuracy is ?1dB.
The Harmonic amplitude accuracy is the same as that of the current or the voltage at the frequency of the harmonic, and the resolution is the same as that of the fundamental (the first harmonic).. The accuracy of the harmonic phase angle is three times as graat as the accuracy of the phase angle between the current and the voltage

Power Factor is calculated as the ratio of Power to Volt-Amperes. It has a range from 0 to ?.0000 and a resolution of .0001 for Volt-Ampere products greater than 7.5% of Full Scale. The resolution decreases as the Volt-Ampere product decreases.

Eight decade Full Scale ranges from 1.0000mW to 10,000W. The ranges are all combinations of a Full Scale Current range multiplied by a Full Scale Voltage range plus a corresponding set of combinations with ten times the sensitivity which occur when the Px10 range is activated. Any Px10 range may be selected when both the Peak Current and the Peak Voltage are less than 0.316 of their Peak Range values.
