相位差測試儀是工業(yè)領(lǐng)域中是經(jīng)常用到的一般測量工具，比如在電力系統(tǒng)中電網(wǎng)并網(wǎng)合閘時，需要兩電網(wǎng)的電信號相同，這就需要精確的測量兩工頻信號之間的相位差。更有測量兩列同頻信號的相位差在研究網(wǎng)絡(luò)、系統(tǒng)的頻率特性中具備重要意義。相位測量的方法很多，典型的傳統(tǒng)方法是通過顯示器觀測，這種方法誤差較大，讀數(shù)不方便。為此，我們設(shè)計了一種數(shù)字相位差測量儀，實現(xiàn)了兩列信號相位差的自動測量及數(shù)顯。近年來，隨著科學(xué)技術(shù)的迅速發(fā)展，很多測量儀逐漸向“智能儀器”和“自動測試系統(tǒng)”發(fā)展，這使得儀器的使用比較簡單，功能越
