The Keysight N6783A-BAT Battery Charge/Discharge Module is a basic, 2-quadrant module designed to be used by battery-powered (mobile) device designers. During the research and development of a mobile device it is necessary to properly validate the battery that will be used in the final design, especially if the design calls for the battery to be permanently installed. Battery validation requires charging and discharging the battery while making measurements of voltage and current to ensure it meets its specifications and will operate in the device as expected. The N6783A-BAT’s 2-quadrant operation allows it to act as a power supply to charge the battery or as an electronic load to discharge the battery. Its built-in, digitizing measurement system allows accurate measurements over the short and long-term. When used in the N6705B DC Power Analyzer mainframe along with the 14585A Control and Analysis software, short- and long-term measurements for battery validation are made easy.
