Thomas Lechner 1GP129 Source measure units R&S®NGU401 and R&S®NGU201 are capable of precise current measurements from sub-microampere up to ampere. This application note provides a tool which generates a voltage or current sweep using the arbitrary function of the instruments. A fast log captures voltage and current values during the sweep. Subsequently the application program determines the voltage

Marc Strohal 1GP128 This application note is about creating your own battery model for the R&S®NGM200, beyond the standard models provided within the battery simulation option NGM-K106. The main purpose is to gradually discharge a battery or a rechargeable battery using the internal QuickArb function. The discharge of the battery can then be recorded using the fast data logging functionality FastLog

Oscilloscopes are increasingly used to analyze pulsed signals such as radar signals for aerospace and defence as well as automotive applications. The oscilloscopes’ wide analysis bandwidth and manifold trigger capabilities, make them a good fit for the increasing demand for higher bandwidths and accurate signal detection in these applications. R&S®VSE vector signal explorer software is a powerful tool

conducted conformance testing according to TS 38.141-1, Rel. 16 Christian Wicke GFM313 3GPP defines the Radio Frequency (RF) conformance test methods and requirements for 5G NR Base Stations (BS) in the technical specifications TS 38.141. This application note describes how all mandatory RF transmitter tests (TS 38.141-1, chapter 6), according to Release 16, can be performed quickly and conveniently

Sebastian Kehl-Waas 1GP124 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

From the expert’s desk R&S®HM8118, measurement, capacitors, inductors, resistors, electric circuits, LCR meters Resistors, capacitors and inductors are the most basic components in electric circuits. It must be ensured that they work properly and accurately. This is usually done using LCR meters, which have become indispensable in the lab and in production. This application card looks at how to perform

Performing precompliance measurements on power supplies requires using a line impedance stabilization network (LISN) for results that can be compared to limit values. While LISNs are standard in any precompliance lab, often no LISN is available for early R&D testing. If high accuracy is not your goal and you just need a simple tool for debugging, you can build your own LISN. Rohde & Schwarz oscilloscopes

based on SCPI command sequences Christian Wicke GFM344 MINX – the M easurement I nstrument N etwork e X plorer – 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

Frederic Schütze GFM336 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

1GP66 Analog-to-digital converters (ADCs) have taken giant steps in speed and accuracy over the past years: Such devices allow high-speed video processing and even software defined radio (SDR) applications, where digitization is being performed at ever-higher intermediate frequencies (IF). This has clearly raised the bar for ADC test equipment, especially regarding the noise performance of the analog
