接好輸入信號線后,為什么示波器沒有任何信號顯示?

    第一,可以嘗試把兩個通道的接地按鈕"GND"依次按下,這時屏幕下方顯示接地狀態,即出現"⊥"標志。這時屏幕上應該顯示兩條水平線。如果沒有顯示,則分別旋轉兩個通道的垂直位移旋鈕“POSITION”,以及水平位移旋鈕“POSITION”,使兩條水平線出現在屏幕上。調好后,再按下“GND”按鈕,撤銷接地。

    第二,轉動一下“INTEN”亮度旋鈕,看是否由于亮度問題使信號線隱藏了。

    第三,旋轉一下“VOLTS/DIV”垂直靈敏度旋鈕,看是否由于靈敏度太小,使信號縱向被拉伸的太高,以至于超出屏幕范圍。

    第四,按一下“CH1”或者“CH2"按鈕,使該處的指示燈亮起來。如果該處的指示燈是熄滅的,表示隱藏該通道信號。
