TRUE RMS/WIDE BANDWIDTH
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.

UNIQUE SAMPLING APPROACH
REMOTE CONTROL
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.
