The HP/Agilent 6811C is a single-phase AC power source combining precision power generation with integrated measurement and analysis. It functions as both a programmable power amplifier and arbitrary waveform generator, enabling simulation of normal and distorted AC line conditions alongside real-time power analysis. The built-in analyzer provides voltage, current, power, and harmonic measurements up to the 50th harmonic with 16-bit resolution, consolidating power sourcing and characterization into one instrument.
