• Dual power analyzer option
• Compatible with 6811C AC power source
• 6811C sold separately
• Provides an additional power analyzer, complete with a precision current shunt, which can be connected anywhere you need it
• Additional analyzer is equivalent in specifications and capabilities to the standard analyzer

The powerful built-in power analyzer in Keysight AC power source/analyzers provides everything that you need to make AC measurements at the AC input to your DUT. For many test scenarios, this is the extent of the AC analysis required. Some test scenarios, however, require AC measurements to be made at both the AC input and the AC output of the DUT. Option 020 provides an additional power analyzer, complete with a precision current shunt, which can be connected anywhere you need it. This second analyzer can even be used for tests where the AC power source/analyzer is not providing power, thus expanding the usefulness of this instrument to many more test configurations. The additional analyzer is equivalent in specifications and capabilities to the standard analyzer.

Using the dual power analyzer option instead of an additional power analyzer instrument externally is more than just convenient. Measurements on all four measurement channels (AC source output voltage and current, and dual power analyzer voltage and current inputs) are inherently synchronized with the AC power source/analyzers output waveform. This precision would be difficult to achieve using separate measurement instruments.

Many electronic products have power-saving or sleep modes. In this mode, the device draws only enough power to be able to recognize a “wake-up” signal, and then execute a smooth “wake-up”. The power drawn in this mode is a critical parameter, and the ability to accurately monitor it is important. The accessory precision current shunt that is supplied with option 020 is mounted in such a way to make it easy for you to replace it with a precision resistor of your choice. By doing this, you can configure the system to accurately monitor extremely low currents. This provides an easy way for you to profile the current draw in all modes of your product’s operation. Since Keysight 6800C Series AC power source/analyzers produce DC power as well as AC power, portable battery-operated products can also be tested with this configuration.

The dual power analyzer option provides many important benefits for UPS testing. Since the key to correct UPS operation is having the output react properly to changes on the input, being able to monitor the output relative to the input simplifies testing. For example, commands are available to enable calculation of UPS transfer time, and the phase difference between the UPS input and output voltage. Keysight AC power source/ analyzers also have programmable output impedance, enabling the UPS designer to verify product stability over a wide range of AC line impedance.
