The following model ac power sources are described in this User’s Guide:
Model Description
Agilent 6811B 0-300 V rms; 375 VA (425 V peak; 40 A peak)
Agilent 6812B 0-300 V rms; 750 VA (425 V peak; 40 A peak)
Agilent 6813B 0-300 V rms; 1750 VA (425 V peak; 80 A peak)
Capabilities
♦ Programmable ac voltage, dc voltage, frequency, phase, and current limit.
♦ Sine, square, clipped sine, and user-definable waveforms.
♦ Programmable output impedance.
♦ 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.
♦ Nonvolatile state and waveform storage and recall.
♦ 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.
All measurements made with 16-bit resolution.
♦ Trigger In and Trigger Out for synchronizing transient events or measurements with external
signals.
♦ Front panel control with 14-character vacuum flourescent display, keypad, and rotary pulse
generators for voltage and frequency settings.
♦ Built-in GPIB and RS-232 interface programming with SCPI command language.
♦ Over-voltage, over-power, over-current, over-temperature, and RI/DFI protection features.
♦ Built-in output and sense disconnect relays.
♦ Output terminals floating with respect to chassis ground.
♦ Extensive selftest, status reporting, and software calibration.
Front Panel/Remote Operation
The front panel has both rotary (RPG) and keypad controls for setting the output voltage and frequency.
The panel display provides digital readouts of a number of output measurements. Annunciators display
the operating status of the ac source. System keys let you perform system functions such as setting the
GPIB address and recalling operating states. Front panel Function keys access the ac source function
menus. Front panel Entry keys let you select and enter parameter values. Refer to Chapter 4 for a
complete description of the front panel controls.
