Battery Simulation With DC Power Supplies

This application note is about creating your own battery model for the R&S^® NGM200 and R&S^® NGU201, beyond the standard models provided within the battery simulation option NGM-K106 and NGU-K106. The main purpose is to gradually discharge a battery or a rechargeable battery using the internal QuickArb function. The discharge of the battery can then be recorded using the fast data logging functionality FastLog.

The recorded data are stored in a .CSV file. This file can then be adapted to be used as a battery model in the battery simulation mode of the R&S^® NGM200/NGU201. For this purpose, Rohde & Schwarz provides a tool for developers to make their work easier. This tool calculates all the data required for a battery model. The following chapters describe the procedure from building an arb file up to working with the tool.
