Oscilloscope Probe Considerations

A basic knowledge of the probe types and their performance capabilities is important because their operation can affect the whole system under test and measurement results obtained.

Studying Subjects Outside Your Specialty

Sometimes we can get stuck in our careers, doing the same things over and over again, day in and day out. One way we can break free from this situation and improve our cognitive abilities is to continue to study and learn new things – even subjects outside of what might be considered our chosen specialty.

Trust but Verify

It’s imperative for successful completion of a testing project that as a compliance engineer or technician leading a product certification effort, you trust but verify the work of testing facilities.

Requirements of Antennas for EMC Testing

Antennas used for EMC testing possess several characteristics which make them ideal for use in a fast-paced, production-like EMC test environment. This article will briefly describe what these characteristics are, starting with the most important parameter – antenna factor.

An Alternative Approach to Specifying an EMI Filter

There has to be a better way of specifying EMI filter performance – one that shows a filter’s effectiveness in real-life situations. It turns out there is a better alternative test method that fulfills this need. This method is the insertion loss test method for non-50Ω systems, located in Annex C of the second edition of EN 55017 (a.k.a. CISPR 17).

EMI Measurement Receiver Requirements (CISPR 16-1-1)

If you’re performing commercial radiated and conducted emissions measurements strictly by the book, you will want to utilize a measurement receiver or spectrum analyzer that fully complies with CISPR 16-1-1.

How EMC Shielding is Defeated

If you’re an electrical engineer and consider proper EMC shielding a mechanical only issue, please reconsider your position and keep reading. Proper EMC shielding is both an electrical and mechanical design issue. Thoughtful coordination between the two disciplines is key to successful EMC shielding implementation on most product development projects.
