兩個(gè)頻率相同的溝通電相位的差叫做相位差，或許叫做相差。這兩個(gè)頻率相同的溝通電，可所以兩個(gè)溝通電流，可所以兩個(gè)溝通電壓，可所以兩個(gè)溝通電動(dòng)勢(shì)，也可所以這三種量中的任何兩個(gè)。 </p> <p> 例如研究加在電路上的溝通電壓和經(jīng)過這個(gè)電路的溝通電流的相位差。假如電路是純電阻，那么溝通電壓和溝通電流的相位差等于零。也就是說溝通電壓等于零的時(shí)分，溝通電流也等于零，溝通電壓變到比較大值的時(shí)分，溝通電流也變到比較大值。這種情況叫做同相位，或許叫做同相。假如電路含有電感和電容,溝通電壓和溝通電流的相位差一般是不等于零的，也就是說一般是不同相的，或許電壓超前于電流，或許電流超前于電壓。

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(shí)，需要兩電網(wǎng)的電信號(hào)相同，這就需要精確的測量兩工頻信號(hào)之間的相位差。更有測量兩列同頻信號(hào)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?cè)O(shè)計(jì)了一種數(shù)字相位差測量儀，實(shí)現(xiàn)了兩列信號(hào)相位差的自動(dòng)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(dòng)測試系統(tǒng)”發(fā)展，這使得儀器的使用比較簡單，功能越

style="text-indent:25px">來間接的測定信號(hào)傳播的時(shí)間，從而求得被測距離的。因此，信號(hào)相位測量的精度也就決定了測距的精度。相位測量技術(shù)的研究由來已久，**早的研究和應(yīng)用是在數(shù)學(xué)的矢量分析和物理學(xué)的圓周運(yùn)動(dòng)以及振動(dòng)學(xué)方面，隨之在電力部門、機(jī)械部門、航空航天、地質(zhì)勘探、海底資源等方面也相應(yīng)得到重視和發(fā)展。隨著電子技術(shù)和計(jì)算機(jī)技術(shù)的發(fā)展，相位測量技術(shù)得到了迅速的發(fā)展，目前相位測量技術(shù)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(shù)的發(fā)展可分為三個(gè)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(duì)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(gòu)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(jì)算機(jī)及智能化虛擬測量技術(shù)，從而**簡化設(shè)計(jì)程序，增強(qiáng)功能，使得相應(yīng)的產(chǎn)品精度更高、功能更全。同時(shí)，各種新的算法也隨之出現(xiàn)。相位測量是正弦信號(hào)經(jīng)過不同的時(shí)間或不同的網(wǎng)絡(luò)后可以有不同的相位。通常所謂相位測量是指對(duì)兩個(gè)同頻率信號(hào)之間相位差的測量。**常見的是對(duì)網(wǎng)絡(luò)輸入與輸出信號(hào)的相位差，即網(wǎng)絡(luò)相移的測量。PLM-100根據(jù)客戶樣品尺寸定制。</p><div
