Wave Scientific now provides an RF shielding effectiveness measurement service for measuring the shielding performance of 19 inch racks, cabinets and other small enclosures. Shielded racks have been widely used in military facilities for many years and are also increasingly used for commercial purposes such as IT and Telecommunication infrastructure. They may be used both for Electromagnetic Compatibility (EMC) purposes and also for protection from Electromagnetic Pulses (EMP).
Measurements of the shielding performance of racks and cabinets can be challenging as their small dimensions limits the size of antennas and other equipment that can be used inside the enclosure. In order to optimise these measurements, Wave Scientific designed a series of small broadband antennas specifically for performing shielding verification measurements of small enclosures. Using these antennas along with with small signal generators and RF amplifiers allow them to measure high levels of shielding performance over a wide frequency range.
They offer measurements either at spot frequencies or with a swept frequency response which can go up to 40 GHz. Measurements can include magnetic and electric field shielding effectiveness as well as plane wave and microwave field attenuation measurements.
The shielding effectiveness measurement of racks and cabinets complements their well established shielding effectiveness measurement service for evaluating shielded rooms and large shielded facilities.
