Topic: Multimedia Equipment, ITE,
and the New CISPR EMC Standards
·
Summary: The International Special Committee
on Radio Interference is in the process of replacing CISPR 13, CISPR 20, CISPR
22, and CISPR 24. Broadcast receivers
and ITE will eventually be subject to the new ‘Multimedia Equipment’ standards
CISPR 32 and CISPR 35. Publication of
CISPR 32 was successfully voted at the end of 2011; CISPR 35 is entering the
voting stages in 2012. This presentation
will review the major changes in the new standards with a particular focus on
the effects for testing ITE.

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.
