The Keysight 6811C is a dual-function AC/DC power source and integrated analyzer for precision power testing and waveform simulation. It synthesizes arbitrary AC waveforms and DC bias across a wide voltage range while simultaneously measuring voltage, current, power, and harmonic content in real time. The instrument integrates power amplification, arbitrary waveform generation, and multi-domain analysis—equivalent to a multimeter, oscilloscope, and harmonic analyzer—into a single benchtop unit. Built-in protection against overvoltage and overpower conditions safeguards connected loads. Communications via LXI-LAN, USB, GPIB, and RS-232 enable remote control and data acquisition in development, qualification, and compliance test environments across avionics, telecommunications, and consumer electronics sectors.
