Keysight / Agilent 6843A Harmonic / Flicker Test System

The Keysight 6843A Harmonic / Flicker Test System is meticulously engineered to facilitate the testing of products for conformity with low-frequency emissions regulations. This comprehensive solution covers quasi-stationary current harmonics, fluctuating current harmonics, and voltage fluctuations and flicker, ensuring compliance with all single-phase regulatory standards.

Combining a standalone AC source, power analyzer, flicker meter, and line impedance network, the Agilent 6843A consolidates all necessary functionalities into a single, compact unit. Each system allows for complete regulatory testing via GPIB and dedicated test system software, bringing unparalleled efficiency to your compliance testing.

This advanced device features low distortion power generation, programmable output impedance, and an accurate measurement system to secure compliance level performance effectively. Unlike multi-unit AC source and measurement configurations, the Agilent 6843A boasts tightly synchronized power generation and measurement capabilities, controlled by a common internal timebase which ensures precise measurement of harmonics within FFT bins, reaching synchronization accuracy of better than 1 ppm.
