Low and selectable test signal current : 1ua to 10 ma 测试信号电流低且可选择: 1a 10ma
The dog was receiving 90 volts of signaling current when the number was called 当拨号时,狗正收到90伏特电流讯号。
Large - signal current 大讯号电流
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,屏蔽线也用于传输信号,这意味着连接两端都不可能真正地接地,事实上,信号电流也许就不存在。
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 计算机电磁波辐射泄漏一类传导发射,通过电源线和信号线辐射;另一类是由于设备中的计算机处理机、显示器信号电流产生的磁场可能透过外套泄漏出来,被卡在线上的电流探头检拾到。
