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. To get to a battery model, a few steps are required. To determine the parameters for the battery model, it is necessary to discharge a battery using a selected method, to record the data and to calculate the model on this basis. With this software, a connection can be established to the instrument, batteries can be measured using various measurement methods, and a model can then be created from these measurements. These models, which are determined from the measurements, can then be simulated with the power supply, thus creating a digital twin of the battery. Using these, test scenarios can be carried out in a safe and reproducible environment.

Battery life time is usually one of the most important specifications for battery-powered devices. Depending on the application, life time requirements can range from tens of hours for typical wearables like smart watches to ten years for smart sensors. Understanding where and when energy is used in order to minimize power consumption is therefore key for any of these devices.The power consumption analysis tool was developed to make it easier for customers to analyze power consumption data collected with either the NGL, NGM or NGU power supplies from Rohde & Schwarz. It allows to easily capture power consumption data and analyze using basic measurements.

Source measure units R&S®NGU401 and R&S®NGU201 are capable of precise current measurements from sub-microampere up to ampere. This application note provides a tool which generates a voltage or current sweep using the arbitrary function of the instruments. A fast log captures voltage and current values during the sweep. Subsequently the application program determines the voltage and current value for each sweep step and plots the results in an I-V curve .The tool can be utilized to characterize all kinds of two-pole devices like diodes, LEDs and solar panels.This application note can also be used in connection with DC power supplies R&S®NGM201 and R&S®NGM202.

This application note is about creating your own battery model for the R&S®NGM200 or R&S®NGU201, beyond the standard models provided within the battery simulation option NGM-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. 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.

Applications requiring higher voltages or currents, or a stack of voltage sources with taps in-between, demand the combination of several DC power supply channels in series or in parallel.All channels of DC power supplies R&S®NGL200 and R&S®NGM200 are isolated against the grounding equipment conductor and against the digital ground of the instrument. Therefore, channels can be connected in parallel for increasing the current capability, or in series for achieving higher voltages or dual-voltage supplies.When a large number of power supply channels is used, it is desirable to have a tool for configuring all instruments and channels from one user interface, and for keeping an overview over the states and measurement values from all channels.The application program of this application note provides such a tool. The document contains background information and user manual for the software.

All channels of DC power supplies R&S®NGL200 and R&S®NGM200 are isolated against the grounding equipment conductor and against the digital ground of the instrument. Therefore, channels can be connected in parallel for increasing the current capability, or in series for achieving higher voltages or dual-voltage supplies. In the case of parallel and serial connections it is usually desired to switch all channels simultaneously on and off for protecting the supplied circuitry and for avoiding overcurrent on other power supply channels.This application note describes how to connect and configure DC power supplies R&S®NGL200 and R&S®NGM200 for synchronized on and off switching of all channels across multiple power supplies.
