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.

based on SCPI command sequences
MINX – the Measurement Instrument Network eXplorer – is a fast, non-invasive discovery and configuration software from Rohde & Schwarz for LAN and USB T&M instruments.Agnostic of instrument model or manufacturer, MINX provides an intuitive graphical user interface with access to powerful configuration, control, results collection and remote display functions.Test or research engineers can quickly setup a collection of instruments to initialise, measure and download results. Universities can configure and manage many instruments together, copying instruments and saving class setups.Besides these core functions, MINX provides an extension mechanism making even more sophisticated instrument operations available by just the click of a single button. Such extended functions are SCPI-based command sequences which can be added by the user on a per-instrument basis and require no software update.This application note describes the different kind of extendable function groups. It will be pointed out how extended functions can be added or edited and which format the script must comply in order to get directly available in MINX.

As the data rates in high-speed digital designs increase, the limits for overall system jitter become tighter. This especially applies to the various components of the clock tree, where the jitter limits for reference clocks, clock buffers and jitter attenuators are even tighter. Due to their high phase noise sensitivity, phase noise analyzers are the instruments of choice for these tests.

What used to be the car radio has evolved from adding a cassette player to state of the art entertainment on the move. All this while keeping driver & passengers connected. The design challenge is to bring all the communication and broadcast standards into a small form factor that fits in the dashboard of the car. The RF modules need to support multiple standards in a single assembly and multiple modules are placed next to each other. The frequencies defined by the RF standards are in very close proximity and hence need to co-exist with each other. Moreover, the antennas inside the car are subjected to cross-coupling effects with mobile devices of passengers. To ensure the RF performance of the infotainment system, all of these scenarios need to be thoroughly tested.This application note highlights some of the RF measurement challenges and introduces Rohde & Schwarz equipment required for relevant RF characterization of car infotainment devices.
