Very often, simple EMC bench-top pre-compliance measurements and troubleshooting techniques can identify issues early when the cost of implementation is substantially lower and design improvements may be made with less impact on schedules. This seminar covers the basics of EMC design, simple bench top measurement methods and includes a number of simple techniques and tools.
Learning Objectives:
Upon completing the course, the participant will be able to:
- Understand the basic theory for the top two EMC issues: radiated emissions and electrostatic discharge
- Make or purchase simple low-cost bench top troubleshooting tools
- Perform simple evaluation and pre-qualification tests to ensure likeliness of compliance
Target Audience:
Analog, RF, Mechanical and Digital hardware design engineers will benefit from this course. A basic engineering background (BSEE or equivalent) is required.
Outline:
Flow of current, signal returns
Differential-/common-mode currents
Signal Spectra
Radiated emissions
Electrostatic discharge
Troubleshooting philosophy
Source-path-receptor model
A low-cost EMC troubleshooting kit
Workbench measurements you can make
2. “EMC Troubleshooting & Pre-Compliance Testing” - Public or In-House Course Summary (1 day):
Note: The following in-house course is offered through Wyatt Technical Services and other quality seminar providers. Please contact me directly for scheduling and costs.
Find out how to use hands-on techniques to measure and
troubleshoot EMI problems before shipping your product (and
design staff) to the EMI test laboratory. We’ll review our
list of “Top 10 EMC Problems” that we have seen in
electronic products and discuss how to select, purchase
and/or build your own near-field probes.
Learning Objectives: Upon completing
the course, the participant will be able to:
- Analyze, measure, troubleshoot and solve an EMC problem
- Understand the basic theory and causes of the top EMC issues: radiated emissions and electrostatic discharge
- Make or purchase simple low-cost bench top troubleshooting tools
- Perform simple evaluation and pre-qualification tests to ensure likeliness of compliance
Target Audience:
Analog, RF, Mechanical and Digital hardware design engineers will benefit from this course. A basic engineering background (BSEE or equivalent) is required.
Outline:
Section 1 - Introduction to EMC – Basic Concepts
Section 2 - Troubleshooting philosophy & Gathering and Analyzing the Data
Section 3 - "Top Ten" EMC Problems
Section 4 - A low-cost EMC troubleshooting kit
Section 5 - Workbench measurements you can make
Section 6 - Design reviews & case studies
Section 7 - Pre-qualification tests you can do prior to going for 3rd-party certification & Setting up a temporary radiated emissions measurement site in your lab

3. “EMC Design for Engineers” - Public or In-House Course Summary (3 days):
Note: The following in-house course is offered through Wyatt Technical Services and other quality seminar providers. Please contact me directly for scheduling and costs. This seminar can also be condensed to a 1-day review with demos.
Because
time-to-market and budget factors often drive many of
today’s high-tech designs, electromagnetic compatibility
(EMC) issues often surface at the last moment in the design
cycle, potentially delaying product introductions. Very
often, simple pre-compliance measurements and techniques
can identify issues early when the cost of implementation
is substantially lower and design improvements may be made
with less impact on schedules. This seminar covers the
basics of EMC design, simple bench top measurement methods
and includes a number of simple techniques and tools useful
in characterizing designs at various stages of development
and will better prepare products for EMC
qualification.
Learning Objectives: Upon completing
the course, the participant will be able to:
- Analyze, measure, troubleshoot and solve an EMC problem in more detail
- Understand theory from a more in-depth view and understand causes of the top EMC issues: radiated emissions and electrostatic discharge
- Make or purchase simple low-cost bench top troubleshooting tools
- Perform simple evaluation and pre-qualification tests to ensure likeliness of compliance
Target Audience:
Analog, RF, Mechanical and Digital hardware design engineers will benefit from this course. A basic engineering background (BSEE or equivalent) is required.
