The HP/Agilent 6811A is a 375 VA AC power source and analyzer engineered for precise generation and measurement of AC power parameters across development, manufacturing, and research environments. It functions as both a programmable power source and real-time analyzer, enabling waveform synthesis, power line disturbance simulation, and detailed harmonic characterization in a single benchtop instrument.
