Sažetak
Electronic devices share the same resources, such as frequency and space. Their ability to sustain the interference from each other is susceptibility. It is important to find which levels of interference disrupt the normal operation of those devices. Is a portable television monitor sensitive to the interference from other electronic equipment operating at same frequencies? What are the signal levels that will cause the interference? To solve this problem, a GTEM-cell structure was used. It has homogenous electromagnetic field area where the equipment under test is placed. Finite element method is used to model the loaded and unloaded GTEM-cell. The interference is measured using the signal generator, Hewlett Packard 8640B and Tektronix CFG250 function generator. The insertion of the TV monitor changes the electric from 2, 25 to 1, 25 mV/m, so the measured results must be calibrated. The sensitivity is 97 dB [ V/m] for lower frequencies and dropping to 80 dB [ V/m] for higher frequencies. Since they are higher than the C.I.S.P.R and FCC levels for radiated emission for A and B class equipment at the test distance of 10 m, the tested TV monitor meets the standard requirements.
