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.

Oscilloscopes are the workhorses for power electronics engineers. With powerful and easyto- use FFT analysis capabilities, their application fields extend to EMI debugging – and that saves a lot of time and money. A typical task is verifying the effectiveness of an EMI filter – early in the development phase.

This application note describes how to measure the control loop stability of switch-mode power supplies to get the best performance and confidence of the design. It will explain the main measurement concept and will guide the user during the measurements and mention the main topics in a practical manner. Wherever possible, a hint is given where the user should pay attention to it to avoid weak measurements. The Rohde and Schwarz buck converter reference board was designed in collaboration with Texas Instruments and is used to illustrate the closed loop measurement in a practical manner.

This educational note covers the theory and practice oscilloscopes based on concrete measurement examples that address authentic everyday tasks.The theoretical portion of this paper begins with an explanation of the basic operating concepts for oscilloscopes, followed by a discussion of the most important parameters to be considered when setting up and performing the exercise measurements. The practical portion of the educational note contains detailed measurement tasks that can be performed by small groups in the university lab. These exercises are intended to demonstrate and reinforce the knowledge gained in the theoretical portion. The exercises build upon one another and demonstrate measurement tasks that are frequently encountered by engineers in daily work.

The R&S®RTB2000 digital oscilloscope lets you share your scope’s display with any computer/projector via LAN or Internet. The oscilloscope comes with an RJ-45 Ethernet jack and a built-in web server (as standard). The screen is displayed via a direct connection to a PC, via LAN or over the Internet.

Deep memory in an oscilloscope ensures that long waveforms are captured with high resolution right down to the details thanks to a high sustained sample rate. Users can be confident that they are not ‘missing anything’. They benefit from viewing longer periods of time and quickly finding signal anomalies or important events.
