From test requirements to test solutions

Speakers: Christina Gessner, Executive Vice President, Rohde & Schwarz and Michael Fischlein, Vice President Spectrum & Network Analyzers, EMC & Antenna Test, Rohde & Schwarz

Complexities in modern electronics continue to grow rapidly in all markets – be it consumer, medical, automotive, industrial, aerospace or military. The interference-free coexistence of numerous electrical and radio products cannot be taken for granted. Only targeted measures for EMC testing & EMI suppression can ensure a safer & more reliable connected world.

At Rohde & Schwarz, we work every day to deliver innovative test solutions in close collaboration with our customers, partners and standardization bodies. This key note will discuss the latest trends influencing EMC & interference testing and how to prepare for current and future industry challenges.

Best practices for EMC compliance testing anywhere, anytime

Speaker: Martin Randrup Villadsen, Rohde & Schwarz GmbH & Co. KG

Increased focus on time-to-market, design complexity, and EMC compliance, often requires optimized “inhouse” knowhow and a structured EMC testing approach.

This presentation explains important considerations before including or enhancing EMC test capabilities in your lab. It explains the typical pitfalls and areas to consider to reduce risks and avoid costly rework. For any operating EMC test facility maintenance is critical to ensuring high quality & reliability, and to guarantee performance according to specifications. Concrete examples from EMC testing facilities will be shared to highlight relevant best practices.

Calibration in EMC. Different faces of one topic.

Speaker: Harald Jäger, Rohde & Schwarz GmbH & Co. KG

The term “calibration” is widely used in EMC – but with different meanings, depending on context. It is either about traceability (on products, services and metrology), correction / compensation of path loss or gain, or performance verification of instruments, to name a few.

This presentation includes a summary of normative requirements and what should be looked at when ordering calibration services. In addition the kinds of measurements that can (and should) be done in an EMC lab to make sure the signal chain works as intended, and how to reveal and localize problems, are also considered.

Test plans for Small Satellites: Meeting demands of New Space

Speaker: Ismael de la Viuda Perez, ALTER TECHNOLOGY TÜV NORD, Spain

Join us for an insightful presentation on what it takes to put Small Satellites into orbit successfully. New space missions demand extreme test conditions and the first step towards a successful test regime is to understand the relevant standards, and to develop a meaningful test plan to meet the requirements of a specific Launch Vehicle. Once you arrive at the test laboratory, procedures and practices will be presented.

Reverberation chambers - Introduction to fast stirring technique

Speaker: Dimitrios Barakos, Comtest Engineering

EMC automotive testing is evolving and moving towards the Reverberation Chamber (RC) method, a trend that is accelerating now the new ISO 11541-5 standard for a full vehicle evaluation has been published. This presentation will begin by outlining the latest updates of the new ISO 11451-5, as well as highlighting the basic steps required to enable full vehicle testing in a reverberation chamber.

The newly introduced closed-loop power control technique (fast-stirring) is of special interest and will be analyzed. Finally, a chamber design fulfilling the requirements of this new test technique backed by experimental data will be presented.

How to qualify devices without accessible antenna ports according to RED and FCC

Speakers: Juergen Kausche, Alexander Scholl, Feng Xie, Rohde & Schwarz

IoT and connected devices are now inundating the market. Many of them rely on wireless technology, such as Wi-Fi. The sleek and stylish designs, often without an accessible antenna port, make these devices more compact and convenient than ever before.

However, this trend poses an additional testing challenge when it comes to demonstrating compliance with RED or FCC regulations; a conducted test, the preferable test method for regulatory tests according to the relevant ETSI standards, is no longer possible. The requirements for an extension of conducted tests to radiated test methods is discussed, and different test methods presented.

EMC standards update – CISPR, ISO

Speaker: Jens Medler and Reiner Goetz, Rohde & Schwarz GmbH & Co. KG

Whatever you are developing, your device must meet requirements set by standard organizations such as IEC, CISPR, ISO, IEEE, CENELEC, ETSI, FCC, ANSI, RTCA or MIL-STD.

The International special committee on radio interference (CISPR) sets emission limits that are needed to protect radio reception from interference. With the evolving use of digital radio services at higher frequencies, there is an increasing demand for emission limits in the frequency range above 1 GHz. Current implementations and proposed extensions in CISPR product standards for above 1 GHz testing are explained.

Unveil the Magic of conducted emissions testing

Speaker: Prof. Dr. Arturo Mediano, Unversity of Zaragoza

Electronic products in many applications (power electronics, automotive, smart industry, lighting, home appliances, etc.) need to comply with conducted EMC regulations.

This presentation explains with a practical demo how state of the art EMI receivers can be used for measuring and debugging problematical conducted emissions in electronic circuits.

Modern EMI receivers provide precise and standard-compliant EMI analysis, fast measurements and automation of these measurements. We will review these advantages (and many more) with an example of electronic equipment failing an EMC test and ways to find a solution after applying a series of debugging techniques.

EMC Immunity testing using multiple signal formats for the real world

Speaker: Dr. Wolfram Titze, Rohde & Schwarz GmbH & Co. KG

EMS tests are performed with different types of RF signals ranging from narrow band to broadband. The interference signals have different modulation characteristics and can consist of multiple tones or even band limited noise which has implications for the selection of a suitable amplifier.

This presentation covers the most common types of interference signal and also new developments from an EMC standards point of view. Which amplifier parameters to look for and how they are specified, will also be covered simplify comparing the different amplifier possibilities.

Updates to EMC standards for medical and in vitro diagnostic equipment

Speaker: Robert DeLisi, UL Solutions

This presentation will detail the latest updates to the EMC requirements for Medical Electrical and In Vitro Diagnostic devices. A review of the major changes to IEC 60601-1-2 and IEC 61326-2-6 will be discussed.

What’s new with EMC tests for vehicles

Speaker: Garth D’Abreu, ETS-Lindgren

Vehicle and component manufacturers invest time and effort in ensuring that EMC tests are as representative and comprehensive as practical. With the introduction of more advanced and automated electrical systems, this is becoming increasingly difficult.

This presentation will look at some of the changes in standard tests as well as some of the other tests available to address these issues.
