The HP/Agilent 6812C is a single-phase AC power source and integrated power analyzer delivering 750 VA maximum output. It generates stable, programmable AC waveforms from DC to 1 kHz, with output voltage to 300 Vrms and peak current to 40 A. The instrument combines arbitrary waveform generation, harmonic synthesis, and transient simulation with real-time power measurement—eliminating the need for separate test equipment. A built-in 16-bit power analyzer measures voltage, current, power (real, apparent, reactive), harmonics to the 50th order, THD, and triggered waveform capture. Store up to twelve user-defined waveforms in non-volatile memory. Optional second power analyzer enables dual-node efficiency testing.
