    <description><![CDATA[
    The double pulse testing (DPT) is crucial to evaluating the switching behavior for metal oxide semiconductor field effect transistors (MOSFET), insulated gate bipolar transistors (IGBT) and wide bandgap (WBG) power semiconductor devices. The slew rate of switching devices is increasing, especially on high-side power transistor where referencing switch nodes creates a fast common-mode environment. Conventional highvoltage differential probes have difficulties obtaining a good measurement with their limited common-mode rejection ratio at higher frequencies.

    <description><![CDATA[
    Within this application note the use of Python programming language to automatize GNSS tests using R&amp;S signal generators is shown. With the R&amp;S PyCharm1 plugin there exists an easy-to-use helper application which highly simplifies the first steps to start script based GNSS testing.Several GNSS use cases of R&amp;S vector signal generators require much repetitive set-up and configuration steps, where human errors may occur. To mitigate these errors Python scripts communicating over SCPI interface may be used to automate the procedures. On the other hand looking up the SCPI-commands one-by-one can be difficult and time-consuming. For an improved user experience JetBrains PyCharm, the RsInstrument Python Module and the R&amp;S Instrument Control PyCharm Plugin may be used to highly simplify the script writing process.This Application Note shows how to install the necessary software, connect to an R&amp;S generator and use the Instrument Control PyCharm Plugin to easily generate user defined Python scripts.

    <guid isPermaLink="false">https://www.rohde-schwarz.com/uk/applications/understanding-noise-in-emi-receivers_56280-1637568.html</guid>
    <description><![CDATA[
    This application note explains how noise sets the sensitivity and usable dynamic range of EMI receivers and how to configure measurements accordingly. It covers the essentials on noise figure and system design for noise reduction, such as the preamplifier placement. The application note explains receiver settings, that all shape the displayed noise floor, and the dynamic-range trade-offs between attenuation, preamplification and preselection. It helps understanding effects on the noise floor and their consequences for compliance EMI measurements and explains how to interpret datasheet values such as DANL. Reading it helps EMC engineers set up receivers for maximum sensitivity, avoid overestimating emissions near the limit, correctly compare instrument datasheet specifications, and distinguish emissions from instrument-generated noise floor artifacts such as spurious responses or input mismatching.

    <description><![CDATA[
    Most modern electronically controlled appliances still switch their loads – such as heating elements and motors – with mechanical relays. Each relay opening or closing generates a short, broadband click that can exceed the disturbance voltage limits of a quasi-peak (QP) detector. Because these transients are intermittent, they are evaluated separately as discontinuous disturbances (clicks) in line with CISPR 14-1/EN 55014-1.

    <description><![CDATA[
    Empowering coastal surveillanceOffshore wind farms, located 10 to 20 nautical miles from shore, present significant communications challenges due to the high density of wind turbines. The turbines create interference and blind spots that hinder effective communications and surveillance at sea. Maintaining reliable communications by extending beyond line of sight (BLOS) coverage and overall communications range is paramount.By integrating VHF/UHF radios into wind turbines, operators can ensure reliable communications even in blind spots, enabling remote control from shore stations to sea and therefore improving operational efficiency.

    <title>Using External DC Bias Current Sources with LCR Meters R&amp;S®LCX</title>
    <link>https://www.rohde-schwarz.com/uk/applications/using-external-dc-bias-current-sources-with-lcr-meters-rs-lcx_56280-1631852.html</link>
    <guid isPermaLink="false">https://www.rohde-schwarz.com/uk/applications/using-external-dc-bias-current-sources-with-lcr-meters-rs-lcx_56280-1631852.html</guid>
    <description><![CDATA[
    Ideal inductors are assumed to have linear behavior, i.e. their properties should not depend on signal amplitudes or superimposed DC bias current. Real inductors often contain magnetic core material, in order to achieve higher inductance within an available volume. All magnetic core materials exhibit nonlinear behavior in the shape of hysteresis and saturation effects. Testing the properties of an inductor depending on test signal amplitude and DC bias current is therefore indispensable for the component characterization.With option R&amp;S®LCX-K108, LCR meters R&amp;S®LCX100 and R&amp;S®LCX200 can superimpose DC bias current up to 200 mA. For higher DC bias currents, an external source is required. This external source can be connected in parallel if it has a sufficiently high impedance over the measurement frequency range.This application note explains how to connect an external DC bias current source, avoid risks and hazards, and perform corrections for optimum measurement accuracy.

    <description><![CDATA[
    Multiple applications such as 5G, satellite communications or radar systems use phased array antennas for beamforming, especially in the millimeterwave (mmWave) range. The individual antenna elements typically use a common signal but with individual phase shift and level ranges. The R&amp;S®ZNA vector network analyzer offers up to four TX paths and eight RX paths for maximum flexibility in a one-box antenna test solution. It easily addresses all interesting frequency ranges such as major 5G FR2 bands as well as Ka and V bands for satellite links.

    <title>Reading Between the Levels: Measuring PAM Signals</title>
    <link>https://www.rohde-schwarz.com/uk/applications/reading-between-the-levels-measuring-pam-signals_56280-1631367.html</link>
    <guid isPermaLink="false">https://www.rohde-schwarz.com/uk/applications/reading-between-the-levels-measuring-pam-signals_56280-1631367.html</guid>
    <description><![CDATA[
    PAM-N signaling is increasingly common across high-speed serial interfaces, from Automotive Ethernet and data center interconnects to storage and general-purpose SerDes links, wherever higher spectral efficiency is required within constrained bandwidth. However, its multi-level nature means that conventional NRZ-based measurement approaches are no longer sufficient. This application note provides a structured, measurement-driven workflow for analyzing PAM-N signals on the R&amp;S®RTP oscilloscope, using MGBASE-T1 PAM-4 as a practical black-box transmitter example. It guides users through the complete signal integrity evaluation sequence, including differential signal setup, CDR-based eye-diagram analysis with both software-based Advanced Eye and hardware-based Live Eye, transition-specific jitter decomposition, channel embedding using S-parameter models, receiver-side equalization, and SCPI-based automation. Advanced Eye provides the stable statistical view needed for detailed eye evaluation, per-eye measurements, and level-dependent analysis, while Live Eye complements this with a real-time view of signal stability, timing variation, and transient behavior as the signal is acquired. By following the workflow, engineers can move beyond a single composite eye diagram or aggregate jitter value and identify where signal degradation originates, whether from level-dependent eye closure, transition-specific timing behavior, channel loss, or equalization effects. The document is useful both as a step-by-step guide for engineers new to PAM-N measurements and as a reference for users targeting a specific part of the analysis workflow. Although MGBASE-T1 PAM-4 is used as the working example, the measurement logic can be transferred to other PAM-N transmitter investigations by adapting the signal configuration and analysis setup to the interface under test.

    <description><![CDATA[
    This educational note provides a practical introduction to Pulse Amplitude Modulation (PAM) signaling and its role in modern high-speed digital communication systems. Starting from the basic principles of PAM-N and the relationship between bit rate and symbol rate, it explains why multilevel signaling has become an important alternative to traditional NRZ transmission in bandwidth-constrained interfaces. The note also discusses key implementation aspects such as coupling, lane configuration, line coding, scrambling, and forward error correction, showing how these factors influence signal behavior and test requirements. A dedicated section on signal integrity analysis explains the impact of reduced eye margins, transition-dependent jitter, and equalization on PAM-N measurements. Using Rohde &amp; Schwarz oscilloscope solutions as practical examples, the note demonstrates how engineers can analyze stacked eye diagrams, isolate individual PAM eyes, evaluate transition-level jitter, and apply equalization techniques for reliable PAM signal characterization.

    <description><![CDATA[
    RF engineers are increasingly confronted with the task of characterizing devices operating in the mmWave range. The vector network analyzer (VNA) R&amp;S ZNA, along with R&amp;S or RPG ZC mmWave converters, provides a broad range of measurement solutions fulfilling this task. This application note is intended to provide help for choosing the right measuring instruments and accessories, interconnecting them correctly, setting up the instruments, calibrating them and finally obtaining measurement results.Both linear and nonlinear measurement quantities are covered. In both categories, one further distinguishes between devices that do not change the frequency of the input signal (e.g. transmission lines, attenuators, amplifiers) and those that do (e.g. mixers, frequency multipliers). Generally, the complexity of setup and calibration is higher in the latter case.The ZNA user interface is designed to assist the user with defining the wanted measurement quantities and their associated parameters like source power, LO frequency, and tone distance for two-tone measurements. It shows the needed setup schematically and proposes how to calibrate this setup including all necessary steps. Many common pitfalls lurking when calibration is completely done manually are avoided by automatic compilation of the calibration.Following this concept, the chapters of this application note first give a brief description of the characterization quantities treated in the chapter, then outline the measurement setup, take a look at calibration and provide examples of measurement results as they appear on the ZNA display.
