Electromagnetic Interference: How to Measure It? .

Numerous standards are considered that limit, all around the world, the maximum levels of noise signals emitted by commercially used equipment. The rapidly growing deployment of microprocessors forces their users to take additional precautions to limit EMI and suppress its negative effect. An interference measurement system is proposed that covers a spectrum from 9 KHz to 1. 3 GHz and can be operated manually or automatically, conforming to all existing standards.
