The Agilent HP 6811B is ideal for applications such as power supply testing, UPS testing, avionics ATE, the testing of power factor corrected equipment and devices. Set up is made easy with the Graphical User Interface, which requires no programming. The Agilent HP 6811B provides a complete AC and DC power and measurement solution with extensive features to protect valuable DUTs. Save space on a lab bench or in a test rack with this flexible instrument. With the built-in power analyzer, this AC Power Source / Power Analyzer combines the capabilities of a multimeter, oscilloscope, harmonic analyzer, arbitrary waveform generator, and power analyzer all in one device. This instrument may also be used to produce DC power, either alone or as a DC offset to an AC waveform. An optional second power analyzer is available, which can be used independently from the source, or for dual-node measurements such as power supply input/output efficiency tests.

Powerful Built-in Measurement Capabilities
Keysight Agilent HP AC sources have extensive 16-bit precision measurement capabilities which would normally require a number of complex measurement instruments, including a DMM (digital multimeter), oscilloscope, power analyzer, and harmonic analyzer. The precision measurements include:

  • RMS, DC, AC + DC voltage and current
  • Peak voltage and current
  • Real, apparent, and reactive power
  • Harmonic analysis of voltage and current waveforms providing amplitude and phase up to the 50th harmonic
  • THD (total harmonic distortion)
  • Triggered acquisition of digitized voltage and current

Using the measurement capabilities of an Keysight Agilent HP AC source simplifies your test setups and helps you obtain accurate data quickly.
