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.

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.

In general, most of the existing electronic devices are connected to the AC mains and require a power conversion stage to convert the AC-Voltage to a smaller DC-Voltage. Voltages and frequencies of the power grid differ between different regions. However, different types of AC-DC conversion stages exist to supply the electronic equipment with adequate DC-power.In AC-DC conversion combined with power levels less than 50W, the flyback converter is a commonplace chosen topology because of its simplicity and its low cost. The majority of consumer products make use of this converter type like wall brick power supplies or power adapters for any consumer application and other type of stand-by auxiliary power supply like used in white and brown goods. In AC to DC converter application, an electrical isolation between input and output is mandatory. The flyback topology provides this galvanic barrier.Beside the common advantages of a flyback converter, it has inherently parasitic components, which typically produce ringing waveforms with considerably high voltage spikes. Without suppressing this unwanted ringing, it may have some negative effect on other components like the switching elements. This ringing can also influence the EMI emissions adversely. Therefore, it is an important task to adequate suppress and damp the ringing effect. This damping circuit is known as snubber circuit and provides this functionality. In the flyback converter, different snubber structures can be applied and each of the structure has its advantage and disadvantage.The demand having a snubber circuit in the power supply topology leads to specific verification methods during the design to obtain a proper and reliable design. These verification methods are the main focus of the discussions within this document.

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.

This application note describes different measurement techniques and methods for an automotive lighting module based on a hybrid controller design. Of course, a lighting module in such an environment has to fulfil requirements according to the automotive standard, which is typically a relatively high-level standard compare to the industry standard. The oscilloscope is a perfect tool for this application to verify the set of requirements because time domain signals (analog and digital) are present in the whole design. Furthermore, measurements in the frequency domain have to be performed, which a modern oscilloscope can fulfil. In addition to the oscilloscope, a programmable power supply supports the measurement in several measurements. The set of requirements are the main reason why a hybrid controller from Microchip is a great choice for this design because it provides tremendous analogue and digital capabilities. The hybrid controller provides beside the analogue functions like an operational amplifier digital functions like analog-to-digital converter and interface functions like UART, CAN or LIN to interact with other systems. The programmable software part is hosted in the digital part. The digital part of the controller implements the communication interface and provides status information to the outer system controller. The light source itself has to avoid any flicker and shall be capable to dim to different lighting levels. Wide input voltage variations and efficiency have to be taken into account during the design of a converter dedicated for automotive applications. Nevertheless, the measurement considerations presented with the design are valid and applicable in other professional lighting industries as well.Thanks to Mr. Andreas Reiter and Mr. Milan Marjanovic from Microchip who provided us with hardware and software and their great expertise to create this application note.
