In this day and age of internet of things, more and more devices are connected to the local network, making it even more difficult for the IT department to monitor them. Rohde & Schwarz instruments are also increasingly accessed via their LAN interface, which provides additional convenience features such as remote desktop, SMB file transfer or a web interface. To make it easier to monitor the use and status of instruments, some devices offer a software option, the Health and Utilization Monitoring Service (HUMS).HUMS can be accessed via SNMP and REST (HTTP) and provides all necessary information about the health status and utilization over time in many details.This application note describes how to access HUMS and what data is provided.

Development of modern EW systems is a complex and expensive process, that requires thorough testing against all requirements during all phases of development. To keep cost under control, system level testing in the lab is key and brings several advantages: test cases can be reproduced under the exact same conditions as often as necessary. System level testing in the lab is often performed in a hardware-in-the-loop (HIL) environment. This application note provides some insight into generating radar signals for hardware-in-the-loop testing with the R&S®SMW200A. An introduction to HIL testing and realtime operation of the R&S®SMW200A is given. The hardware and software interface, the PDW format and synchronization and timing mechanisms are described. Additionally, various example scenarios and detailed information about intermediate calculations are provided. The application note also provides information about system requirements for advanced PDW streaming with multiple emitters on multiple parallel streams.

Automated test equipment (ATE) is a cornerstone in production facilities. Devices under test (DUT) have to be measured according to various limits to ensure safe and reliable operation for the user. A production facility must ensure that these tests are performed properly and cover all the necessary test cases. However, the tests must also be executed with sufficient speed. Oscilloscopes (e.g. the MXO series from Rohde & Schwarz) are often a typical part of ATE and can improve the workflow with a dedicated “waiting for trigger” signal.

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.

Determining the noise figure of a component can be difficult in unshielded lab environments. Measuring small noise figures (less than 3 dB) and reproducing the results is sometimes not possible. These difficulties are caused by interference effects (electric fields) that can occur in any environment. A suitable remedy is a measurement environment able to shield the Device Under Test (DUT) against all interfering fields in the range up to 3 GHz. When used in conjunction with a spectrum analyzer and Noise Measurement Software FS-K3, the Shielded Box ZA-SB10 provides a complete noise measurement system.

Using option ZVR-B4 (Frequency Converting Measurements), a ZVR Vector Network Analyzer can be used for measurements on frequency converting devices such as mixers and amplifiers. Using the ZVR's ARBITRARY mode, the source and receiver frequency ranges of the ZVR's generator and receiver, plus for two external signal generators, can be defined independently. As a result, mixer and intermodulation products such as conversion loss or sampling mixers, can all be measured. Used together with option ZVR-B6 (Reference Channel Ports), group delay measurements can also be made on frequency converting devices.
