Fast Emission Measurement in Time Domain

According to the standards, emission measurements are carried out in the frequency domain using a test receiver. In this paper the setup and algorithm of a measuring system in the time domain is presented. The advantage of this system is, that measurements can be done approximately 10 to 20 times faster. The paper shows a proposal for the use of the system in standard EMC tests. Since EMC tests are quite expensive, this measuring system offers an easy possibility to reduce EMC related costs of product development.
