Description
The ac source combines three instruments in one unit as shown in the following figure. The function
generator produces waveforms with programmable amplitude, frequency, and shape. The power
amplifier amplifies the function generator signal to produce the ac power for your application. The
measurement functions range from a simple readback of rms voltage and current, to sophisticated
capabilities such as waveform analysis.

The following model ac power sources are described in this User’s Guide:
Model Description
Agilent 6814B 3000 VA single –phase operation
Agilent 6834B 1500 VA/ phase for three-phase operation
(4500 VA for single-phase operation)
Agilent 6843A 4500 VA single-phase operation
Capabilities
♦ Programmable ac voltage, dc voltage, frequency, phase, and current limit.
♦ Sine, square, clipped sine, and user-definable waveforms.
♦ Voltage and frequency slew control.
♦ Synthesized waveform generation for high resolution and accuracy in frequency, low waveform
distortion, and glitch-free phase transitions.
♦ Step and pulse output transients for generating surge, sag, dropout, and other line disturbance
simulations.
♦ Nonvolatile list programming for generating complex output transients or test sequences.
♦ Three-phase/single-phase output capability (Agilent 6834B only)
♦ Extensive measurement capability:
• Ac rms, dc, ac+dc voltage and current and peak current.
• Real, reactive, and apparent power.
• Harmonic analysis of voltage and current waveforms gives amplitude, phase, and total
harmonic distortion results up to the 50th harmonic.
• Triggered acquisition of digitized voltage and current with extensive post-acquisition
calculations.
