Automated measurement of emissions from equipment and systems

Many users of automated emission test systems misunderstand automated emission testing as "testing by pushing a button and leaving the system alone". This is only possible if the user has assured that measurement times or scan rates have been set to measure the specific emission from the EUT correctly. It requires a knowledge of the specific emission which can be obtained by a manual (or interactive) measurement of the emitted signal types. The emitted signal may consist of a mixture of broadband and narrowband signals. Narrowband signals may he amplitude or pulse modulated. This specific knowledge has to be transformed into settings of the automated test system.
