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.

Rohde & Schwarz offers a wide range of essential lab equipment, like power supplies, LCR meters and power analyzers. To enhance the versatility of these instruments, a selection of application programs is available. These application programs typically remote-control equipment for more complex tasks like sweeps, logging and battery testing.In a larger lab there may be a larger number of such instruments present, and a selection of available application programs installed on a PC. In such a case it is desirable to have a kind of dashboard providing an overview over both, including version check and links to documentation on the Rohde & Schwarz website. The R&S® application dashboard for power supplies and meters is providing this functionality. The application document contains the description and user manual for the software. Furthermore a package is provided containing installers for all related application programs.

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.

Electronic systems like electronic control units (ECU) must pass several stringent qualification tests in order to be approved for automotive use. These tests include a reverse polarity test which is specified as part of ISO 16750‑2. In line with the specification, the electronic module must withstand a negative supply voltage for a specific time without suffering any damage. The R&S®NGU401 source measurement unit (SMU) is ideal to perform this task, plus it provides automated testing capability.
