Description
The Agilent 6812B 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. And protect your valuable prototypes and assemblies with the extensive set of protection features.
Save space on a lab bench or in a test rack with this flexible instrument, which can take the place of an AC source, DC source, powerful arbitrary waveform generator, as well as a sophisticated power analyzer. 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.
The Complete ac Power Test Solution
Since your product will have to operate in the real world of unpredictable ac power, you need to design and verify its correct operation under a wide range of ac power inputs. Brownouts, dropouts, sags, and other irregularities are not unusual in many communities today. Agilent ac sources have the features needed to easily accomplish this test goal either in an R&D environment or on the manufacturing test floor. If you plan to sell your products in a worldwide market, you will also need to test them at the line voltages and frequencies that they will eventually operate at. There is also additional testing needed to meet regulatory requirements for sale into some countries.
Agilent ac sources offer a complete solution for ac power testing, helping you to simplify this important task. These instruments combine the features of a power amplifier and arbitrary waveform generator to give you the ability to do all of the tests that you need. There are many standard preprogrammed waveforms, or you can use the transient generation system to simulate sophisticated and repeatable ac line disturbances. dc power can also be generated, either as a dc offset or as a pure dc signal.

- Product may be operated between dc and 45 Hz subject to certain deratings. Measurements may be extended to 4.5 Hz at full accuracy only by selecting a digitization rate of 250 μ seconds per point. Frequency content of the measured signal must be limited to 4 k Hz or less to avoid aliasing effects.
