Scanning of electromagnetic radiation for EMC and data security purposes

Popis výsledku v původním jazyce

A semi-automatic measurement system and diagnostic tool for localization of radiating parts of electronic devices in near-field was developed. A near-field scanning of electromagnetic emission is performed by the system. Maximal spatial resolution of thescanning is 0.2 mm which is sufficient for exact localization of radiating parts in the most cases. Frequency range of the measurement is from 30 MHz to 3 GHz. The advantage of the system is simplicity of implementation, as it is based entirely on commercially produced devices. The test receiver Rohde & Schwarz ESPI7 was used for the measurement of radiation level. The advantageous functions of the receiver such as fast frequency scan and simultaneous measurement with three detectors was utilized. Thescanning procedure is controlled by a program which leads a user throughout all measurement steps. The program was made in Agilent VEE Pro. Important part of the measurement is processing of the measured data. Therefore, software for effe
