Low and selectable test signal current : 1ua to 10 ma 測試信號電流低且可選擇: 1a 10ma
The dog was receiving 90 volts of signaling current when the number was called 當撥號時,狗正收到90伏特電流訊號。
Large - signal current 大訊號電流
With unbalanced interconnects , the fact that the shield carries signal current means that it cannot be truly " grounded " at both ends or there would , de facto , be no way for signal current to exist 非平衡的方式中,屏蔽線也用于傳輸信號,這意味著連接兩端都不可能真正地接地,事實上,信號電流也許就不存在。
One kind of electromagnetic radiation leakage of computers is conducted emission , with radiation through power wires and signal lines ; the other kind thereof is due to that : magnetic fields produced by signal current of computer processors and displays in equipment may leak through the cable sleeves and be picked up by the current probes clamped on lines , and the signals received may be sent to the specially - made receiver for processing and restoration 計算機電磁波輻射泄漏一類傳導發(fā)射,通過電源線和信號線輻射;另一類是由于設備中的計算機處理機、顯示器信號電流產(chǎn)生的磁場可能透過外套泄漏出來,被卡在線上的電流探頭檢拾到。
