The Keysight AC6918H is an 18 kVA three-phase AC power source and integrated analyzer for demanding test environments. It combines AC and DC sourcing with multimeter, harmonic analyzer, and power analyzer functions in a single instrument. The system generates programmable AC, DC, and AC+DC waveforms up to 5 kHz, supports single-, two-, and three-wire output configurations, and delivers up to 320 Vrms with 60 A per phase maximum current. Built-in power line disturbance simulation, harmonic analysis to the 50th harmonic, waveform generation, and soft start/stop protection make it suitable for avionics qualification, electric vehicle charger development, and aerospace system testing.
