  1. This instrument can meter the electric level, frequency spectrum, carry to noise ratio, a / v, cobbly ratio, voltages of the ac trunk line and the battery. furthermore it can display the above information on the lcd and store them in the eprom

    該場強儀可以對有線電視系統的電平、頻譜、載噪比、 a v比、系統不平度、交流干線和電池電壓等進行測量，並通過液晶顯示，結果保存於eprom中。
  2. Its principle is as following : acquire and modulate the analog signals from sensors placed in environments through daq device on real time, then transit the information to computers by pci bus ; in the other hand, noise information tested with sound level meter is passed through interface rs - 232 to computers

    本系統工作原理為：通過多功能數據採集卡採集來自各種傳感器所採集的各檢測對象的模擬信號，對信號進行調理，通過pci系統總線傳遞給計算機；而噪聲則通過聲級計由rs - 232傳入計算機。
