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.

More functions, greater processing power and growing data rates make high-speed system-on-chips (SoCs) power designs challenging. The increasing number of power rails that supply the various function blocks of modern CPUs, GPUs, FPGAs, ASICs and such require precise sequencing during power-up and powerdown. Supply voltage levels are also lowered to reduce power dissipation inside the SoC. Power integrity requirements are stricter and more supply current is needed on power rails. Multiphase buck converters continue to grow more popular for high-current power rails. The converters have many benefits, but designers also face challenges when it comes to power design and validation testing.

Software tool for fast and repeatable optimization of signal analyzer RF front-end settings

The signal conditioning in the RF front-end of signal analyzers is crucial to achieve the best performance with respect to image-suppression, noise-floor, dynamic range and other RF-key parameters.Precise signal levelling is especially important for complex measurements like Error-Vector-Magnitude (EVM). To minimize the measurement uncertainty from test system contributions over a wide range of different levels, the RF front-end needs to be adapted continuously according to the signal characteristics, signal power and frequency - ideally using an automatic levelling algorithm.This document describes the approach of a waveform specific, on-site characterization of the signal analyzer: For each waveform and frequency of interest, the instrument is evaluated in a first step. With this additional data, a fast and repeatable auto-levelling can be performed during the actual measurement.

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.

Synthetic aperture radar (SAR) uses radar wavelengths for airborne or spaceborne ground mapping. The resolution of the SAR ground map depends on the range and cross-range SAR processing resolution. Cross-range resolution is determined by integrating pulses along a flight path for a period of time to create a synthetic aperture. Longer synthetic apertures result in finer cross-range resolution. Range resolution is achieved by radar waveform bandwidth in the form of a linear frequency modulated (LFM) chirp. Wider bandwidth enables finer range resolution.

Comprehensive test solutions guide for production and R&D

Small cell is a compact base station with smaller form factor and lower transmission power in comparison to the conventional macro base station. It covers relatively small area and serves less users. Usually, small cell can be integrated into the existing mobile network. By the evolution of radio access technology, the role of small cell has been changing through the evolution path. In the 2G/3G time, its role was to provide coverage in corner cases. Later during LTE, networks are not just providing coverage but capacity too. Small cells were then used to provide the addition capacity where required without adding additional spectrum. Now in 5G era, network operators use densification as an important strategy to provide seamless 5G services which demand coverage, capacity and performance too. With use cases requiring the 5G millimeter wave (mmW) rollouts, it makes sense to use small cells for densification due to the propagation characteristics of mmW.In this application note, we will shed light on the testing aspects of a small cell throughout the product life cycle with particular focus on the production test solution for the small cell device under test (DUT) in FR2 (frequency range 2, mmW frequency band) in Over the Air (OTA) environment for option 6 split based on radio communication tester R&S®CMP200 and OTA chamber R&S®CMQ200. The document is complemented with more insights into test solutions used in typical R&D test applications towards the second half of the application note.
