主要標(biāo)準(zhǔn):
CISPR 11: Industrial, scientific and medical (ISM) radio-frequency equipment and similar equipment –Radio-frequency disturbance characteristics –Limits and methods of measurement
CISPR 12: Vehicles, boats and internal combustion engines—Radio disturbance characteristics—Limits and methods of measurement for the protection of off board receivers
CISPR 13: Sound and television broadcast receivers and associated equipment –Radio disturbance characteristics –Limits and methods of measurement
CISPR 14-1:Electromagnetic compatibility . Requirements for household appliances, electric tools and similar apparatus -Part 1: Emission
CISPR 15: Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment
CISPR 22:Information technology equipment – Radio disturbance characteristics –Limits and methods of measurement
應(yīng)用特點(diǎn):
用來測量被試設(shè)備(EUT)在正常工作狀態(tài)下通過電源線、信號(hào)/控制線對(duì)周圍環(huán)境所產(chǎn)生的傳導(dǎo)干擾是否符合要求。如果干擾信號(hào)過大,就會(huì)影響整個(gè)電網(wǎng)的用電質(zhì)量,從而干擾到其他電器的正常運(yùn)行。在實(shí)際測試時(shí),受試物在上電期間可能會(huì)產(chǎn)生很強(qiáng)的瞬態(tài)信號(hào),可能會(huì)沖擊并損壞測試接收機(jī)的 RF 輸入端口,因此一般需要在 AMN 和接收機(jī)之間串一個(gè)能抑制瞬態(tài)信號(hào)的脈沖限幅器。如果受試物電流過大(例如大于 400A)或者無法使用 AMN 進(jìn)行測量時(shí),可以使用 CISPR 16-1-2 規(guī)定的高阻抗電壓探頭進(jìn)行測量。
主要測試設(shè)備:接收機(jī)、人工電源網(wǎng)絡(luò)、電壓探頭、EMC測試軟件等
測試環(huán)境:屏蔽室
