Measuring spurious emissions from amateur radio transmitters can become surprisingly complex once cable losses, analyzer settings, attenuation, bandwidth selection, and regulatory requirements enter the picture. To help RF experimenters and engineers make better measurements, Elektor presents a practical webinar with Sebastian from Baltic Lab on Thursday, June 4, 2026.

In this session, Sebastian will explain how spurious emissions testing for amateur radio transmitters should be performed under ETSI EN 301 783-1 [PDF]. The emphasis will be on real measurement practice rather than broad EMC theory.

Sebastian will cover what spurious emissions are, why they matter for spectrum integrity, and how apparently sensible spectrum analyzer measurements can still fail under scrutiny. Topics will include resolution bandwidth, attenuators, cables, correction factors, frequency spans, test loads, and the analyzer settings that can distort or invalidate a result.

The webinar is aimed at engineers, advanced hobbyists, RF experimenters, amateur radio operators, and anyone using a spectrum analyzer for compliance, pre-compliance, or serious bench measurements. Even if you are not working directly to ETSI EN 301 783-1, the session should be useful for improving general RF measurement technique.

Giveaway

Elektor is giving away one tinySA Ultra+ ZS407 Spectrum Analyzer (see Related Products below) during the live stream. This compact handheld spectrum analyzer and signal generator is a good fit for a session on RF measurement practice, giving users a practical way to explore signals, frequency spans, analyzer settings, and bench-level measurement pitfalls.

About Sebastian

Sebastian is from Baltic Lab and works with practical RF, EMC, and test and measurement topics. His approach focuses on correct measurement technique, standards-aware testing, and the kinds of real-world mistakes that can creep into otherwise reasonable-looking results.

This amateur radio transmitter testing webinar is part of Elektor’s ongoing focus on practical engineering skills, bench techniques, and test and measurement methods that hold up outside the comfort of a neat block diagram.
