Well-matched RF ports are a crucial aspect to any RF system. Matched ports, for example, protect amplifier output ports from reflected power overload. This undesired reflected power could destroy the whole amplifier. Matched ports also maximize power transmission, effectively extending the battery life of wireless products such as those made for the internet of things (IoT).

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.

30 dBm + 30 dBm = 60 dBm? It is well known that it is not as easy as that.
This application note supplies a free of charge software tool that can be used to add or subtract an arbitrary number of powers. In addition, the software can be used to convert power and voltage units from the linear to the logarithmic scale (and vice versa), convert linear power and voltage ratios to decibels, and convert a VSWR to other reflection quantities.

In civil aviation, instrument landing system (ILS) transmitters use antenna arrays to provide guidance to approaching aircraft. ILS performance strongly depends on the precise alignment of the magnitude and phase of each element in an antenna array. The R&S®ZNH handheld vector network analyzer with a built-in source allows fast, convenient on-site measurements on the ILS antenna system.

R&S®Server-Based Testing helps reduce test times for workloads that can be parallelized. 5G New Radio (5G NR) multicarrier signals are an ideal workload because each component carrier can be analyzed independently and in parallel. In an example EVM measurement, scenario test times are reduced significantly even when receiving I/Q data from just a single instrument.

Automating measurement setups is advantageous for multiple reasons. It saves time in case of repeated measurements and in hazardous environments, instruments can be operated from a distance. The measurements are repeatable because they are always performed with a defined procedure, leading to higher test confidence.But in remote control applications, users often perceive synchronization and binary transfers as challenging. Therefore, this application note focuses on binary transfer of data to and from the instrument and shows code example to demonstrate the ease of use.
