This paper presents the measurement of aggregated conducted emission in the frequency range of 9 kHz to 150 kHz produced by multiple compact fluorescent lamps (CFL) and how it equates to a multiple power converter system. Discrepancies in peak emission measurement results related to this application are illustrated to understand the underlying issue related to volatility of frequency components. Furthermore, this knowledge analyzes the relation of electromagnetic disturbances with respect to different topological network connections. The final presented results constitute theoretical description and statistical information about the characteristics of conducted emission measured in this multi-converter system.

ZAbstract -For measuring the maximum electromagnetic emissions around equipment many test methods use the frequency domain, traditionally using a super-heterodyne test receiver. However, for large equipment under test the frequency domain method is very time consuming when the measurements are performed at low frequencies, below 150 kHz, where small bandwidth and thus long measurement time is needed. Timedomain measurements are now replacing the traditional superheterodyne receivers, but the commercial time-domain receivers still use a first mixer stage. However, at low frequencies, low cost digitisers can do the same job directly in the baseband. Using fast signal processing, this method allows to continuously measure the radiated magnetic field around the equipment under test. Combined with position tracking, this allows to identify areas of maximum emissions very fast. These positions are then used to obtain a more detailed spectral analysis of emissions by increasing the measurement time over those spots. In result, the whole measurement procedure can be significantly optimized by spending less time over areas of lower interest, and putting more focus on areas of potentially high emission levels. This paper presents the concept as well as an experimental comparison of three antenna movement approaches satisfying the NRE01 and RE101 radiated emissions measurement procedures.

“…Interference at low Pulse Repetition Frequencies (PRFs) is said to be subjectively less annoying on radio reception than that at high PRFs. Therefore, the quasi-peak response de-emphasizes the peak response at low PRFs, or to put it another way, pulse-type emissions will be treated more leniently by a quasi-peak measurement than by a peak measurement [5].…”

The role of light-emitting diode lamps and radio frequency lighting controls is to reduce the energy consumption. The increase of lighting network complexity determines the increase of EMC noise emission. Being familiar with measurement systems is important for making correct measurement and for understanding the results of the measurement. Correct interpretation of measurement results is the first step in choosing the best suppression method. The suppression method depends on the common mode and the differential mode of noise type and on the frequency of signal noise.
