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.

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.

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.

The application program of this application note provides a tool for cycling battery samples, using two-quadrant DC power supplies from Rohde & Schwarz. The batteries can be repeatedly charged and discharged while collecting information about open-circuit voltage, loaded voltage and internal resistance, depending on the charged and discharged capacity. The tool provides a variety of charts for displaying the collected data. It can be used for characterizing battery samples, as well as for creating battery models which can be used in the battery simulations of R&S®NGU201 and R&S®NGM200.This tool is meant for the use by knowledgeable experts. The application note does not provide instructions on how to properly charge and discharge batteries.

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.Note: More advanced tools are available with application notes 1GP130 (Battery Cycle Tool) and 1GP136 (Battery Simulation).

This application note applies to DC power supplies R&S®NGL200, R&S®NGM200, R&S®NGP800, R&S®NGU201 and R&S®NGU401, as well as LCR meters R&S®LCX100 and R&S®LCX200. It provides an overview over ethernet-based remote services provided by the referenced R&S® instruments. These services comprise an instrument web page, VNC remote control and FTP file transfer between the instrument and a remote computer. The application note gives instructions on how to set up the instrument and the remote computer in order to be able to utilize these services.

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.
