·         Topic: Debugging Embedded Wireless EMI Problems

·         Abstract: As RF technologies become more ubiquitous, the embedded RF designer is challenged to make complex multi-domain measurements across the state logic, analog, and RF domains of their design.  Whether verifying RF performance during low battery simulations, adjusting range and timing of pulsed transmission, or attempting to correlate unintentional emissions to assure regulatory compliance, understanding the complex behavior in embedded RF designs has often required complex test setups and careful calibration.

New integrated tools that provide time correlated measurements across the embedded design are now available to simplify the most complex multi-domain challenges:

- Digital protocol command to RF event latencies in embedded RF designs
- Understanding VCO settling, timing, and turn-on attributes
- Correlating unintentional EMI harmonics to transient logic states and pulsed conditions

This technical presentation will discuss new measurement advances in the field of multi-domain measurement correlation.

·         Topic: Why use reverberation chambers for radiated emissions?

·         Abstract: Unlike a semi-anechoic chamber a reverberation chamber provides a test electromagnetic environment, as a superposition of plane waves with random phase, resulting from repeated reflections from conducting surfaces intentional formed to create a complex environment. The statistical isotropy, random polarization, and uniform electromagnetic environment of a reverberation chamber permit a robust, all aspect angle test without the requirement for rotation or translation of the equipment-under-test.  This talk will discuss the potential benefits of EMC testing in a reverberation chamber.

·         Topic: Evolution of Early Radio Design

·         Abstract: From sparks and crystals to tetrodes and superhetrodynes; the 1920’s represented a decade of unprecedented advances in radio technology and circuit design.  We’ll take a trip through evolution of broadcast radio designs of the period leading up to the advent of the superhetrodye receiver.  There will be working examples of wireless apparatus’ and early receiving sets from the beginning of public broadcast to the early 1930’s along with many of the components used during this era.  Join us for a look behind the knobs and the Bakelite panels.

·         Topic: Automotive EMC

·         Abstract: This topic covers EMC approaches applied to automotive systems, from the conventional "legacy" systems to the latest developments in electric vehicle propulsion. There is discussion about the unique environment that automotive systems function in and how some of the methods used to meet automotive system functional requirements can determine the vehicle's EMC characteristics. Typical automotive EMC requirements are identified and examined, along with "case studies".

·         Topic: Engineering Aspects of PCB level EMC Design

·         The PCB design is a complex cooperation between electrical, mechanical, thermal, SI,
PI and EMC design. In a practical design, the EMC design engineer has to make trade-offs and understand the relative impact of different design choices. The lecture is an overview of the typical PCB design aspects and their role for the EMC performance. Among the aspects discussed are placement, stack-up, routing, decoupling, and grounding aspects. The design of the I/O ports, in order to pass the emissions and immunity tests is also discussed in greater detail.
