Cost-effective uses for near-field probing
in every project stage; for emissions, immunity, and more
This module has been completely revised for 2020 and has almost doubled in size.
This module is designed to help people understand Close-field EMC probing (often called near field probing). This is a useful qualitative method to quickly identify emissions problems. It can quickly reveal weak points for immunity, when used with transient and/or radio-frequency (RF) generators and it can help design PCBs, shielding and much else.

Electromagnetic Engineering (EMgineering) is the basis for proven good design practices for signal integrity (SI), power integrity (PI), and the control of EMI emissions and immunity (EMC).
Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment (products, systems, installations, etc.) to meet functional (i.e. SI/PI) specifications and conform to EMC standards, directives and other requirements.
Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability.
We also cover basic good electrical safety engineering; and the Risk Management of Electromagnetic Disturbances / EMI, whether for Functional Safety or other types of risk.Join EMC standards TODAY!
