Product Overview

The Agilent / HP 6843A Harmonic / Flicker Test System is designed for testing products for compliance to the low-frequency emissions regulations for quasi-stationary current harmonics, fluctuating current harmonics, and voltage fluctuations and flicker. The Agilent 6843A provides full power coverage of the single phase regulatory standard requirements. The HP 6843A combines all of the generation and measurement functionality reqiured for full complance testing in one compact unit. Each 6843A includes the capabilities of a standalone ac source, power analyzer, flicker meter, and line impedance network. All regulatory testing functionality is available via the GPIB and test system software.

Low distortion power generation, low and programmable output impedance, and an accurate measurement system assure complinace level performance.

Unlike multiple-box AC Source and measurement configurations, the power generation and measurement of the 6843A is controlled by a common internal timebase and is truly synchronized. This allows precise measurement of harmonics since they will fall directly within the center of the FFT bins with with a sync with a synchronization accuracy better than 1 ppm.
