PERANCANGAN MAGNETIC FIELD PROBES UNTUK PENGUJIAN RADIATED EMISSION
AbstractScience and technology are growing so rapidly that electronic equipment and instruments are widely used, but the emission of electromagnetic radiation is also introduced and occurs at the same time so that it continues to potentially cause health problems. One effective way to detect EMI emissions is by conducting Pre-compliance testing using a tool in the form of probes, namely Magnetic Field Probes. The role of pre-compliance testing provides an initial indication of whether the equipment might meet requirements when Full-compliance testing is carried out. When measuring using M1 Loop - H Field and Probe 1 twist and Probe 2 windings as is known from this final project (TA) it is expected that Magnetic Field Probes sensitivity is above -68 dBm. After measurement using M1 Loop - H Field and Probe 1 Windings and Probe 2 Windings as expected above -68 dBm which is -26,36 dBm. When testing it is known that the sensitivity of Probe 2 coil is better than Probe 1 coil. This is because the number of turns used is different, which is designed by using two turns where the magnetic field generated by one coil is reinforced by other turns. The magnitude of the magnetic field depends on the number of turns, the more the number of turns, the greater the value of the magnetic field produced. Then, electronic devices are used as objects for measuring emission of electromagnetic radiation, namely EM Demo Board, PABX and Led Driver. The standard used is EN 55011 (Standard CISPR11) with a frequency range of 30 MHz to 3 GHz.
