How to locate EMI emissions with near-field probes: Part 2
Now that you know a little theory of near-field measurements, how do you use near-field probes and a spectrum analyzer to help you troubleshoot and mitigate emissions issues? Remember, as mentioned in Part 1, that deciding whether to use an H-field or E-field probe depends on whether you’ll be probing high switching currents — di/dt […]
IEEE EMC Symposium 2023: Presentations
Long known for its academic papers and presentations, the EMC+SIPI Symposium in 2023 featured more practical tutorials and workshops than ever before. See photos from the technical sessions and workshops.
EMC chamber fits into small spaces
ETS-Lindgren’s SpaceSaver 26H reduces the footprint needed for 3-m emissions testing. EMC test chambers take up space. It’s what they do. Physics has something to do with that. Even so, ETS-Lindgren has developed the SpaceSaver 26H EMC chamber, which the company installed at the E3 Compliance test lab facility in Grand Rapids, Michigan. The chamber […]
Data line, EMI filters feature improved low-frequency performance
ITG Electronics has introduced a new and improved version of its signature series of Data Line and Electromagnetic Interference (EMI) Filters. The company’s F2780Y001L-02X Series offers enhanced performance over a lower frequency spectrum. In addition, an input-side keystone jack helps make them easier to install and integrate. The F2780Y001L-02X Series contains 2-pi low-pass filter and […]
Power line EMI filters reduce EMI emissions in MRI shielded rooms
ITG Electronics has introduced a series of UL and cUL Listed MRI Room Power Line EMI Filters that significantly reduce EMI emissions in MRI Shielded Rooms. Designed to eliminate interference with MRI scanning equipment, the range comes in single, two- and three-line varieties. The single-line F1770, two-line F2771 and F3772, and three-line EMI filters are […]
What are some common EMI/EMC tests?
An EMC test is known as Electromagnetic compatibility, a certification for electronic devices to maintain their limitation of electromagnetic waves. As discussed in the previous article, there are two types of EMC tests: emission (EMI) and immunity (EMS). EMI (Electromagnetic Interference) tests measure the magnetic waves emitted by the device, and EMS (Electromagnetic Susceptibility) tests […]
The basics: What is EMC?
EMC stands for Electromagnetic compatibility, which means that a device is compatible with (i.e., no interference is caused by) its electromagnetic (EM) environment. It does not emit levels of EM energy that generate electromagnetic interference (EMI) in other devices in the vicinity. Electromagnetic interference (EMI) is the interference caused by one electrical or electronic device […]
