HP / Agilent 6812A AC Power Source / Analyzer 750 VA

The HP/Agilent 6812A is a single-phase AC power source and analyzer combining power amplification, arbitrary waveform generation, and harmonic analysis in one instrument. It delivers up to 750 VA with output voltage control from 0–300 Vrms and current delivery to 6.5 A (at 300 Vrms) or 13 A (at 150 Vrms). The unit generates sine, square, clipped sine, and up to 12 user-defined arbitrary waveforms with maximum harmonic distortion of 0.25% at 50/60 Hz. Transient modes support step, pulse, and list-based waveform programming with voltage and frequency slew control. DC output capability extends to 425 V DC at 5 A DC.
