The Efficient Method of Ambient Signals Cancellation in EMC Interference Measurements

Popis výsledku v původním jazyce

The paper deals with some aspects of EMC interference signal measurements in the presence of undesired ambient signals that appear mainly by an open field test site measurement. The method for efficient ambients cancellation is described, and discussed in the article from theoretical, as from practical point of view. The method, which is in the form of special hardware/software utilities already implemented in some modern electromagnetic interference (EMI) receivers, is based on ambient signals storingin an internal receiver memory and then on their "subtracting" from actual measured signals. Results of this concept depend first of all on the character of actual ambients signals, and on their time and frequency stability. After the theoretical background of the concept is stated, its effectiveness was checked in series of EMI measurements by using the EMI Spectrum Receiver from the Seaward Ltd. in the frequency range from 9 kHz to 1000 MHz. By this, we have used various types of simul
