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.

An ever-increasing requirement for data on mobile networks, driven by a myriad of applications from HD video on the move to autonomous vehicles and Industrial IOT, means a part of the new 5G network is to be deployed at mmWave frequencies, with a 26 GHz pioneer band defined for the UK between 24.25 - 27.5 GHz.This near 10-fold increase in frequency over 4G networks opens several challenges, both in the design and implementation of the required sub-components, network infrastructure and end user equipment, and in parallel in the test and measurement approaches used to drive these developments.In this presentation, we will introduce some of the main challenges in test and measurement of a device at these frequencies. We will then present the testing of a 26-28GHz pioneer band dual channel amplifier evaluation module using 5G NR test waveforms.

Many applications in aerospace and defense as well as in mobile communication require a defined magnitude and phase relation between several signals, for example, to design a smart antenna array and it's distribution network, or to ensure accurate phase alignment between different transmitter or receiver chains of T/R modules. Magnitude can be measured with spectrum analyzers or power meters. For phase measurements, a vector network analyzer is the easiest, fastest and most accurate instrument.This application note shows how to measure the phase accurately between several signals using vector network analyzers of the R&S®ZNA, R&S®ZNB and R&S®ZNBT families.

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.

This application note describes a software application that can be utilized in conjunction with Rohde&Schwarz Signal- and Spectrum Analyzers and Signal Source Analyzers to capture and analyze transient signals. The software application takes advantage of the instrument’s IQ memory buffer of up to 705 Msamples to capture and analyze IQ signals in the time domain and / or frequency domain. This is useful for measuring lock time, analyzing radar pulses, finding spurious transients, and other measurements similar in nature to these. This application can be used with R&S®Signal Source Analyzer FSUP and R&S®Signal and Spectrum Analyzers FSQ, FSU, FSG, FSV.

Receiver diversity improves reception quality by using multiple antennas with a preferably low correlation factor between each other. This results in a more robust handling of multipath signals, since a deep fade will then not affect all received signals at the same time. However, the compact dimensions of handheld devices can introduce unwanted correlation due to their dense antenna spacing. In this case, the popular diversity test setup consisting of several independent transmitters will no longer serve the needs of a realistic simulation, since correlation effects have to be taken into account here. A clever solution is to operate the R&S®SFU in split-fading mode in combination with a second transmitter. This can be another R&S®SFU, the R&S®SFE, the R&S®SFE100 or the R&S®SMU200A. In this way, two diversity signals of adjustable correlation for any common broadcast standard are coded in realtime, while their individual multipath profile is precisely specified by the extensive features of the R&S®SFU fader module.
