Influence of interface cables termination impedance on radiated emission measurement
Interface cables and especially their arrangement and terminations significantly affect the results of the radiated emission measurement of tested equipment. Two types of shortened two-wire interface cables were surveyed to obtain the influence of cable's termination. Two analyses, based on theoretical knowledge, were performed - the analysis using numerical simulation and the measurement of input impedance of the cable using network analyzer. The methods of analysis were verified and compared with real radiated emission measurements. Finally, the influence of cable termination was obtained and discussed.
