Pengujian Conducted Emission Pada Laptop Sesuai Standart CISPR 22
Abstract
Abstrak Perangkat elektronik dapat menghasilkan conducted emissions saluran yang menyebabkan gangguan pada perangkat lain yang terhubung dengan distribusi listrik yang sama. Berbagai macam teknik mitigasi conducted emissions dilakukan untuk meminimalisir gangguan yang dihasilkan. Pada PA dilakukan pengujian conducted emissions pada laptop sesuai dengan standard CISPR 22. Dimana laptop dipilih sebagai equipment under test(EUT) yang terhubung dengan LISN sebagai filter noise dari luar. Pengujian ini bertujuan untuk mengetahui tingkat emisi yang dihasilkan dari sebuah laptop apakah memenuhi batas standard emisi atau tidak. Tiga jenis laptop yang digunakan dalam pengujian adalah laptop A, B dan C. Dari hasil pengujian didapatkan bahwa saat wifi dalam kondisi on pada laptop A, terdapat 10 frekuensi yang mengalami peningkatan EMI pada frekuensi 970,875 KHz, 1,269375 KHz, 1,344 MHz, 1,418625 MHz, 1,493250 MHz, 1,6425 MHz, 4,552875 MHz, 4,77675 MHz, 4,851375 MHz, 20,970375 MHz. Dengan rata-rata mengalami peningkatan sebesar 3,6 dBuV. Pada laptop B tidak mengalami peningkatan ketika wifi dalam kondisi on. Pada laptop C ketika wifi dalam kondisi on mengalami peningkatan EMI terdapat 3 frekuensi pada frekuensi 523125 KHz, 1,418625 MHz, 2,2395 MHz. Dengan rata-rata mengalami peningkatan EMI sebesar 2 dBuV. Kata kunci: conducted emission, frekuensi , CISPR 22 , EUT Abstract Electronic devices can produce conducted emissions this can cause interference to other devices connected to the same electricity distribution. Various types of conducted emissions mitigation techniques are carried out to minimize the resulting disturbances.Test conducted on PA was carried out on laptops in accordance with CISPR 22 standard. Where the laptop was selected as equipment under test (EUT) connected to LISN as a noise filter from the outside. This test aims to determine the level of emissions produced from a laptop whether it meets the emission standard or not. The three types of laptops used in the test were laptops A, B and C. From the test results, it was found that when the wifi was on on the laptop A, there were 10 frequencies that experienced an increase in EMI at a frequency of 970,875 KHz, 1,269375 KHz, 1,344 MHz, 1 ,418625 MHz, 1.493250 MHz, 1.6425 MHz, 4.552875 MHz, 4.77675 MHz, 4.851375 MHz, 20,970375 MHz. With an average increase of 3.6 dBuV. On laptop B, it doesn't increase when the wifi is on. On C laptop when wifi is on on condition there is an increase in EMI, there are 3 frequencies at frequency 523125 KHz, 1,418625 MHz, 2,2395 MHz. With an average EMI increase of 2 dBuV.
