5. Alternator whine
以上來(lái)自Motorola 的一分規(guī)范文檔, 要求車充做如上測(cè)試.
但是規(guī)范上沒(méi)有解釋不了解
其含義?
以及具體的測(cè)試方式?
尋求幫助
請(qǐng)教幾個(gè)MOTO關(guān)于車充的測(cè)試方式(專業(yè)詞匯)?~~
全部回復(fù)(8)

borwnout:滅燈overload:過(guò)載cranking:啟動(dòng)loaddump:切斷負(fù)載alternatorwhine:這個(gè)不好翻譯,能把原句搬上來(lái)嗎
多謝回復(fù).
上訴單詞是MOTO車充測(cè)試中模擬汽車電源環(huán)境的測(cè)試.
部分原句:
Alternator Whine Procedure
A simulated alternator whine waveform is superimposed on the battery voltage at the DC power input of the product under test, at nominal battery voltages of 13.8 and 16V DC. The waveform is a 1/2 wave rectified sine wave of 1 volt amplitude with postive going spikes of 3 volts amplitude. The waveform is swept from 200 to 4000Hz .

這個(gè)是剛看到的文檔,
看來(lái)是模擬點(diǎn)煙頭輸入紋波的,
另外: 這一句整句如如何理解
The waveform is a 1/2 wave revtified sine wave of 1 volt amplitude with postive going spikes of 3 volts amplitude.
