Agilent Dual Power Analyzer Description
The Agilent Technologies Dual Power Analyzer Option 020 is available on the following ac sources:
Agilent 6811B AC Power Source (375VA)
Agilent 6812B AC Power Source (750VA)
Agilent 6813B AC Power Source (1750VA)
Agilent 6813B Option 019 AC Power Source (2000VA)
Option 020 consists of an additional Power Analyzer input on the back of the ac source, an external
current shunt, and a cable to connect the current shunt to the ac source. Option 020 adds the following
capabilities to the above listed ac source models:
• Voltage and current measurement inputs on the rear panel, with capabilities similar to the output
voltage and current measurements available in standard Agilent ac sources.
• The ability to use any shunt for the external current measurement, allowing current measurements
over a very wide range of magnitudes.
• Precisely synchronized measurements between the rear panel Power Analyzer input and the ac source
output. This is possible because the Power Analyzer input has its own dedicated measurement buffer.
• New measurement commands that may be used in evaluating uninterruptible power supplies (To
measure transfer time, peak voltage, and phase locked loop performance for example).
• Frequency modulation of the ac source output.
As shown in the following figure, the Agilent Dual Power Analyzer also includes an Agilent supplied
current shunt, which must be connected to the output of the equipment under test to make accurate
voltage and current measurements. The specifications and supplemental characteristics of the Agilent
Dual Power Analyzer are documented toward the end of this document.

Agilent Option 022 Description
Option 022 is simply an Agilent 6813B Option 019 AC Power Source combined with an Agilent Dual
Power Analyzer Option 020. All of the Option 020 information in this document also applies to units that
are configured as Option 022 units.
