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.
