Testing

The effectiveness of different materials for shielding can be tested using near field probes and your vector network analyzer (VNA).

Compliance testing can be a very expensive endeavor and also a very confusing one. And when it comes to lithium ion cells and batteries, the expense is magnified by the number of samples needed for testing.

The International Electrotechnical Commission (IEC) has released IEC 60749-28:2017 

Known mechanisms that couple lightning surges onto communication cables, and how these mechanisms apply for the specific case of Ethernet cabling.

This article documents the role of margin demonstration in system-level EMC testing: how and why they were first instituted, and how they have evolved over time.

It is very common for people doing simulations to make a measurement of a similar set up to validate the simulation. This is a reasonable precaution since modern simulation tools will give a very accurate answer to whatever question it is asked.

Modeling and simulation is a complex topic, usually left to experts of the EMC field as the amount of knowledge and understanding that goes into creating a model can be tremendous.

There are several scenarios where integrated circuits (ICs) are mounted on printed circuit boards (PCBs) which might be charged-up and experience CDM-like events.

This article will define the test requirements, and discuss the methods used to obtain results. Limitations of the equipment used will also be discussed, so that lab personnel can be made aware and do their best to minimize tolerance errors.

Quite often, we are asked about the most common deficiencies that are cited by assessors during A2LA assessments to ISO/IEC 17025:2005.
