style="text-indent:25px">相位差測量兩個正弦電量可以是電壓和電流，或者一個是電壓，一個是電流等，對應點通常是從負到正的過零點，相當于正弦電函數(shù)的初始相位角。相位差的單位是度或弧度，正負號表示超前或滯后關系。一種由于被測相位差正弦電量的頻率范圍很寬，所以通常根據(jù)頻率選擇測量方法和儀器。常用的方法有直接法和間接法。一種直接法：用指針式相位計、數(shù)字相位計等**儀器或用負示波器測量相位差。當使用陰極示波器時，將兩個相同頻率的正弦電壓信號分別加到示波器的X軸和Y軸上。然后兩個正弦電壓之間的相位差為∮=電弧正弦（B/α）。</p><p style="text-indent:25px">來間接的測定信號傳播的時間，從而求得被測距離的。因此，信號相位測量的精度也就決定了測距的精度。相位測量技術的研究由來已久，**早的研究和應用是在數(shù)學的矢量分析和物理學的圓周運動以及振動學方面，隨之在電力部門、機械部門、航空航天、地質勘探、海底資源等方面也相應得到重視和發(fā)展。隨著電子技術和計算機技術的發(fā)展，相位測量技術得到了迅速的發(fā)展，目前相位測量技術已較完善，測量方法及理論也比較成熟，相位測量儀器已系列化和商品化?，F(xiàn)代相位測量技術的發(fā)展可分為三個階段：***階段是在早期采用的諸如阻抗法、和/差法、三電壓法、比對法和平衡法等，雖然方法簡單，但測量精度較低；第二階段是利用數(shù)字**電路、微處理器、FPGA/CPLD、DSP等構成測相系統(tǒng)，使測量精度得以**提高；第三階段是充分利用計算機及智能化虛擬測量技術，從而**簡化設計程序，增強功能，使得相應的產(chǎn)品精度更高、功能更全。同時，各種新的算法也隨之出現(xiàn)。相位測量是正弦信號經(jīng)過不同的時間或不同的網(wǎng)絡后可以有不同的相位。通常所謂相位測量是指對兩個同頻率信號之間相位差的測量。**常見的是對網(wǎng)絡輸入與輸出信號的相位差，即網(wǎng)絡相移的測量。軸角度測量范圍：0°~180°

相位差測試儀是工業(yè)領域中是經(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、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，隨著科學技術的迅速發(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
