Elektor will host a live webinar on Thursday, 4 June 2026 focused on spurious emissions testing of amateur radio transmitters under ETSI EN 301 783-1.
Sebastian from Baltic Lab will join Elektor host Brian Tristam Williams for the session, which is aimed at engineers, RF experimenters, amateur radio operators and anyone using a spectrum analyser for compliance, pre-compliance or serious bench measurements. The session is designed to deal with practical measurement practice rather than broad EMC theory.
Elektor’s webinar with Baltic Lab’s Sebastian covers standards-aware spurious emissions testing for amateur radio transmitters.
This is a €50 show, brought to you free by Elektor Academy Pro.
The €50 webinar is free to attend thanks to Elektor Academy Pro. The live stream is scheduled for 16:00 CEST, 14:00 UTC and 10:00 EDT on 4 June.
The webinar centres on ETSI EN 301 783-1, which covers technical characteristics and methods of measurement for commercially available amateur radio equipment. That makes the topic relevant beyond the amateur radio bench: many of the same issues appear in RF product development, prototype validation and pre-compliance checks where the measurement setup can determine whether a result is useful or misleading.
Topics for the session include what spurious emissions are, why they count for spectrum integrity, and how apparently sensible measurements can still fail under scrutiny. Sebastian will cover resolution bandwidth, attenuation, cables, correction factors, frequency spans, test loads and spectrum analyser settings that can distort or invalidate a reading if they are not handled properly.
The point of the webinar is that transmitter testing is not simply a matter of connecting RF hardware to an analyser and looking for unwanted peaks. Cable loss, attenuator choice, reference bandwidth, test power conditions and uncertainty all affect the outcome. For teams working on RF hardware, the same discipline is useful whether the end target is a formal test house, a repeatable internal procedure or a more credible engineering judgement before a design is sent out for external assessment.
The focus also fits Elektor’s wider programme of engineering events and test-related coverage. As previously covered by eeNews Europe in its Red Pitaya Lab Talk item, recent sessions have put practical instruments and measurement workflows in front of engineers rather than treating test gear as a black box.
Elektor will also give away one tinySA Ultra+ ZS407 Spectrum Analyzer during the live stream. The compact handheld spectrum analyser and signal generator ties directly into the subject matter, giving users a practical way to explore frequency spans, analyser settings and bench-level RF measurement pitfalls. For engineers and advanced hobbyists, the spurious emissions testing webinar should be a useful reminder that reliable RF measurements depend as much on setup and method as on the instrument itself.
