On-Site
Courses
Background
Your staff will be taught how EMC and EMI control
is done in the conceptual stages, design, production,
installation, diagnostic or upgrade and retrofit
stages of the life cycle of your products or
systems. This is done completely at your own
facility, so there is no travel and per diem
cost or lost time traveling. The biggest cost
of training your engineers and technicains is
not the cost of our course. To offset any perceived
"lost work time" by those taking the
course, part of the in-house training time is
earmarked to solve your existing project or
system EMI problems. Projected overheads and/or
actual hardware are critiqued by the instructor
in front of the class with student participation
including Q & A, strategies and options.
This also helps apply and bind what has been
learned.

Getting Started
Getting started on an in-house
course is quite simple. Just follow the steps
below:
To get started, just call 1.800.565.2787
and ask for Allan Kiesler. Alternatively, you
can send an e-mail to akiesler@aEMCs.com. You
will be referred to an engineer who will personally
help you select the right course or tailor a hybrid
for you.
2002
Scheduled Courses
aEMCs and Don White Consultants
are pleased to present the Spring 2002 Course
Schedule in EMI Control, Wireless EMC Engineering,
EMC for Managers and MIL-STD-461E & -464 Compliance
About Our All-New
Courses
Objectives:
Rapid technology transfer to arm design, systems
and installation engineers and technicians to
solve EMI-related problems with supporting rationale.
What these courses
are not:
- About EMI-related
regulations and compliance testing
- Academic and
theoretical emphasis, per se
- EMC information
space fillers and "fluff"
- EMC rules and
techniques without rationale
What these courses provide:
- A blend of the
analytical and pragmatic
- Solutions to
real-world, today and tomorrow problems
- Design and installation
focus and tools
- "War stories",
strategies and solutions with rationale
- Consulting during
the course on your project
Course Strategy
and Expectations:
All Don White Consultants courses are a blend
of the analytical and the pragmatic, with supporting
rationale. Concepts are highly illustrated to
enhance your grasp and are buttressed by math
models, where practical, to facilitate understanding.
Sometimes, computer-software is run to portray
inputs with output results and "what-if" gaming.
Re physical reliability, photographs of hardware
are shown with installations, where available,
or hardware show-and-tell is used and passed
around in class. The concept objective is total
multimedia immersion and is far superior and
faster than traditional training with "hands-on"
demonstrations.
Q&A During
a Course:
Your questions throughout the course are extremely
important to us. In addition to providing us
feedback, others in the class may have a similar
question. Remember, there is no such thing as
a stupid question. Only a poor answer.
Consulting During
a Course:
Bring your unsolved problems to the course.
If of general interest, you may be invited to
present them before the entire class for critique
and solutions. Otherwise, discuss them with
the instructor at breaks, before the class begins
or at the end of the day.
What you take
home:
- An exhilarating
experience with new tools and solutions
- An understanding
of EMI-control Methodology & Procedures
- Two highly-illustrated
handbooks, one of which is
The EMC, Computer
and Telecom Encyclopedia,
3rd Edition
by Don White
- Problem-solving
software on CD-ROM
- Eagerness to
solve old/new existing problems back at the
plant
About the Instructors: Don White, Bill Duff
and Bill Parker
- Seasoned, international
EMC gurus
- Collectively
taught 19,000 engineers and technicians worldwide
- Written 16 EMC-related
books
- Masters at technology
transfer
- Two are past
IEEE/EMC Presidents
Who Should Attend:
- Electronics Engineers
and Technicians
- Mechanical and
Packaging Engineers
- Engineering Managers
- Selected Marketing
and Sales Engineers
- Others with "need-to-know"
Course Guarantee:
All DWC courses are guaranteed to provide substantial
technology transfer. In the extremely unlikely
event, you are not pleased at any time during
the course, advise the instructor and your tuition
will be refunded in full.
