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.

5G is the fifth generation of wireless communication technology supporting cellular networks. From GSM (2G) through to LTE (4G), each generation addresses technical challenges not overcome by its predecessor. As with previous generations, 5G requires new mobile devices and new base stations (BTS).Unlike previous generations, the use of radio beams in 5G requires completely new approaches with regard to the compliance, coverage, and quality of service testing.The new air interface is called 5G NR ("new radio"). This application note describes the measurement challenges of 5G NR and makes clear the benefits of using a monitoring receiver for measuring 5G signals.Real-world examples explain how to perform various key 5G measurements. The final section covers further 5G measurement possibilities using R&S products. "Over-the-air" (OTA) measurements are essential in 5G. This means staff from regulators and operators must work in unknown radio environments that vary according to location (e.g. urban or suburban) and mission (e.g. 5G BTS compliance testing or interference hunting). Measurement equipment must operate in a wide range of scenarios (close to the mast and far from the mast) and offer user-friendly functionality that enables the required measurements.Considering current global deployment trends, this paper focuses on the FR1 frequency band (sub 6 GHz).

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.
