CISPR is the acronym of Comité International Spécial des Perturbations Radio, [1] or the International Special Committee for Radio Protection of IEC. CISPR Standards aim to the protection of radio reception in the range 9 kHz to 400 GHz from interference caused by operation of electrical or electronic appliances and systems in the electromagnetic environment.
Like all compliance testing, it is important that the test equipment, including the test chamber or site and any software used, be properly calibrated and maintained. Typically, a given run of tests for a particular piece of equipment will require an EMC test plan and a follow-up test report. The full test program may require the production of ...
Usually, the electrical appliance must be factory tested with standards for conducted emission, as the list of common EMC test standards denotes. Moreover, different manufacturers hold different versions of these standards as fit best to their appliances and warranty schemes. Fig. 2. Conducted Emissions from a commercial DC buck converter
Product specific tests are instead defined in standards such as EN 50130-4 for alarm systems, EN 50121-4-2 for railway applications or IEC 60601-1-2 for medical equipment. The product, or equipment under test (EUT), is seen from an operator's point of view during test. The EUT is therefore in its operational mode and testing does not include ...
A line filter (aka EMC filter, EMI filter, RFI filter) is an electronic filter that is placed between the mains electricity input and internal circuitry of electronic equipment to attenuate conducted radio frequencies radio frequency interference (RFI), also known as electromagnetic interference (EMI).

One of the busiest travel days of the year got off to a rough start due to a "technical issue" that disrupted American Airlines flights across the U.S.
A TEM or transverse electromagnetic cell is a type of test chamber used to perform electromagnetic compatibility (EMC) or electromagnetic interference (EMI) testing. It allows for the creation of far field electromagnetic fields in a small enclosed setting, or the detection of electromagnetic fields radiated within the chamber. [1]
Those poor saps. Holed up in that swanky hotel in suburban Dallas trying to wade through this mess. Rivalry Week came and went, and now the 13 members of the College Football Playoff selection ...
