Rohde & Schwarz R&S RTO/RTE EMI Testing Step-by-Step Guide

About this manual

This guide explains how R&D engineers can integrate EMI testing into the product design cycle using the R&S RTO/RTE digital oscilloscopes. It covers locating emissions with near‑field probes, capturing signals with advanced trigger options, and analyzing results with FFT gating and history functions.

The document provides practical settings such as frequency span selection, realtime bandwidth (RBW) tips, vertical sensitivity ranges, and probe recommendations, helping engineers reduce costly redesigns and achieve pre‑compliance or compliance with EMC standards.

Frequently asked questions

What frequency span should I set for a design that does not involve RF modules?

A full span of 0 Hz to 1 GHz is usually sufficient for designs without RF modules.

What RBW setting is suggested for measuring radiated emissions with a 30 MHz span?

Use an RBW between 100 kHz and 1 MHz.
