應(yīng)用特點(diǎn)Application Characteristics:
對于照明燈具等可能產(chǎn)生低頻磁場的設(shè)備,需要采用CISPR16-1-4標(biāo)準(zhǔn)規(guī)定的環(huán)形天線系統(tǒng)測量其低頻的磁場輻射。被測物(EUT)放置在三環(huán)天線的中間,三環(huán)天線將X方向、Y方向、Z方向低頻磁場分量轉(zhuǎn)換為RF信號,并通過同軸開關(guān)切換三個(gè)通道,輸送到EMI接收機(jī)進(jìn)行測量。測試需在屏蔽室內(nèi)進(jìn)行。

主要測試設(shè)備:接收機(jī)、三環(huán)天線、EMC測試軟件等
測試環(huán)境:屏蔽室(高度大于3.3m)
