Abstract :
According to the standards, emission measurements are carried out in the frequency domain using a test receiver. In this paper the setup and algorithms of a measuring system in the time domain is presented. The advantage of this system is, that measurements can be done approximately 10 to 100 times faster. The emphasis in this paper is set on algorithms to increase the measurement accuracy of narrowband and broadband signals. Furthermore, the choice of the best capture time for the time domain measurement is described.
