Techday IEMN et Rohde & Schwarz

R&S FSWX is the first multichannel signal‑and‑spectrum analyzer equipped with multiple input ports and an innovative internal multi‑path architecture. This design introduces a novel cross‑correlation capability that overcomes the limitations of conventional spectrum analyzers. The presentation will walk through the flexible multi‑path architecture, illustrate how the modular input‑port topology can be reconfigured for diverse test setups, and showcase real‑world use cases.

This talk introduces the fundamentals of traceable calibration for RF power and highlights Rohde & Schwarz power meter technologies. We will explore the concept of metrological traceability, discuss the calibration hierarchy from national standards down to end-user measurements, and demonstrate how Rohde & Schwarz products and services ensure accuracy, reliability, and compliance at every level.

Phase noise is a fundamental determinant of signal integrity in modern electronic systems such as communications, radar, and navigation, where excess noise can corrupt data transmission and degrade accuracy. This presentation reviews the principles of phase‑noise measurement and compares the two primary instrument families, versatile spectrum analyzers and dedicated high‑accuracy phase‑noise testers, highlighting their respective advantages and limitations. By understanding the capabilities of each instrument, researchers and engineers can select the most appropriate solution for their specific measurement needs, ultimately enabling more reliable system design, optimization, and performance.

With the increasing complexity of modern-day experiments, reliable information recovery is more important than ever before, in terms of signal strength, artefact-free measurements or other environmental decoupling. In this presentation, you will learn how smart signal processing, based on repetition rate using lock-in technique, allows for denoising the signal of interest in realtime. From there, demodulation at multiple frequencies, optimized control in a determined bandwidth or resonance tracking becomes possible from a few Hz to multiple GHz over a wide applications range that will be briefly illustrated.
