Primer

A power sensor is a fundamental measurement tool in RF engineering. However, today's marketplace is filled with myriad choices, and many are making bold claims about attributes such as measurement speed and readings per second. As a result, it can be difficult to cut through the hyperbole and determine which sensor will actually meet the requirements of a specific measurement.This primer outlines the basics of RF power sensors and highlights a few key characteristics that will help you select the best one for each application. The narrative has three parts. First, we focus on choosing the right type of sensor: multipath, wideband, average power and thermal can satisfy slightly different measurement needs. The second section covers the five major attributes of sensor performance, and what to look for relative to your requirements. Finally, we outline three ways to integrate a sensor into your measurement application.

10BASE-T1S Ethernet enables the integration of diverse sensors into an automotive-Ethernet vehicle supply system, for example short-range radar sensors for detecting blind spots or ultrasonic sensors for the parking assistant. For reliable operation of the functions, data transmission over 10BASE‑T1S Ethernet must be assured at all times and in every climatic environment. Functionality must be tested during development and in production. Only 10BASE-T1S Ethernet interfaces that have passed compliance testing in line with IEEE 802.3cg can be deployed in vehicles. Consequently, vehicle manufacturers and their suppliers need measuring equipment that allows them to perform these tests quickly and reliably.

Spectrum clearance in mobile networks is becoming ever more important as operators use new bands that previously contained other services. This is particularly important for the 5G NR rollout. 5G NR has already initiated a worldwide deployment of TDD networks in an unknown radio environment where unwanted transmitters can create uplink interference masked by downlink signals, making interference hunting particularly demanding. Automated detection of interference signals before a network switches on can be a big help in addition to traditional manual techniques.

Simulation can be a big time-saver when designing EMI filters for DC/DC converters. Power supply control chip vendors offer various filter design tools that provide reasonable design choices for filter simulation before any hardware prototype is available. However, simulated results can differ significantly for different tools if simulated models are not accurate or do not cover all the relevant components. Performing a hardware measurement to evaluate the effectiveness of a simulated EMI filter is therefore indispensable.
