(1) FCC and Canadian
EMC requirements
(2) European EMC Directive
(3) Mil 461 and RTCA EMC requirements
(4) Other world EMC regulations
(5) Real world measurements and levels
2.
Interference overview
a. Typical
noise path
b. Wavelengths, bandwidths and dB's
c. Overview of radiated interference
3.
Grounding
4. Cabling - principles from crosstalk to how shielding works
5. Passive components
5:00-6:30
pm Laboratory Tour
Optional
tour of a modern EMC test facility
Day
2
Electric and magnetic
fields from simple circuits
Fields radiated
by non-sinusoidal sources
General strategy
for low emission product design
Controlling radiated
emissions at the device
Digital circuit
noise and layout
Filtering - how
filters work and ways they can be used in your design
Emission control
in motherboards & backplanes
Day
3
Hands-on calculations
made throughout the day
Controlling radiated
& conducted emissions from switch mode power supplies
Reducing emissions
from cables and packaging
Calculating emissions
for a digital circuit
Shielding
Calculation of
emissions for enclosures
Troubleshooting
radiated & conducted emissions
Electrostatic discharge
(ESD)
Case study and
validation of results
Day
4 - The Workshop
Using
an example of a real life product and following typical design principles,
students will:
Develop a block
diagram
Determine the
product's EMC parameters
Using our proprietary
computer programs (a copy of which you will take home) calculate the
probable emissions and immunity characteristics of the:
a. circuit boards
b. power supply
c. I/O lines
d. enclosure
While
meeting the North American and European EMC regulations, students will design/analyze
a unit consisting of:
A motherboard
with microprocessor, clocks, digital inputs and outputs
A power supply
Cables with and
without shielding for the digital and analog inputs and outputs
An enclosure
An external keyboard
An interface to
a video monitor
Students
will go through the product's requirements and calculate its estimated emissions
and immunity, providing rationale for various decisions.
When
you leave this seminar/workshop, you should be ready to lead a design team
with a high degree of confidence that your products will meet their EMC
requirements.
Included
with the seminar/workshop:
A large workbook
of the slides used in class
Worksheets to do
the calculations
Computer software
to calculate harmonics from PCB, cable emissions & cabinet shielding
Textbook Design
Techniques for Controlling Radiated Emissions 2nd edition
Specific sample
problems and calculations
Lunch each day
What
to bring:
Your desire to
learn
Calculator
A laptop running
Word, Adobe Acrobat, Excel and a CD/DVD drive. (A laptop is useful,
but not required)
