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

style="text-indent:25px">滯后的相位值都為π的一半，或者說90°.在計算電路電流有效值時，電容電流超前90，電感落后90，可用矢量正交分解加合.加在晶體管放大器基極上的交流電壓和從集電極輸出的交流電壓，這兩者的相位差正好等于180°.這種情況叫做反相位，或者叫做反相.正弦量正交（90°）和反相（180°）都是特殊的相位差.目前，國內(nèi)相位差測量儀生產(chǎn)廠家或研究單位明顯存在著技術老化問題，其采用的器件、方法和技術與技術先進國家有較大的的差距。而**近發(fā)展的先進的計算機技術、電子技術等卻由技術、資金、管理等方面的原因未能應用于相位測量技術，因此國內(nèi)相位測量的水平與國外水平有著相當大的差距。同時，隨著**和科教等領域的發(fā)展，迫切需要高精度高性能的相位測量系統(tǒng)，而且在一些特殊工程領域，還需要測量儀器具備其它特殊功能。由此可見，為縮小這些差距，對高精度相位測量算法的研究和相位測量系統(tǒng)的設計刻不容緩。本文介紹的是一套較完整的高精度相位差測量儀，提高相位及頻率參數(shù)的測量精度，并擴展測相系統(tǒng)功能，由移相網(wǎng)絡模塊、相位差測量模塊及頻率測量模塊三大部分構成，其系統(tǒng)功能主要是進行相位差測量及頻率和幅度測量。型號PLM-100 技術參數(shù)：主要測試項目：偏光片吸收軸角度、偏振片偏振方向、波片快軸方向。江蘇國產(chǎn)相位差測量儀</p><p style="text-indent:25px">高精度軸角度相位差測量儀相位差(0 20000nm)。江蘇RETS-100L相位差測量儀技術指導</p><p> 相位噪聲通常界說為在某-給定偏移頻率處的dBc/Hz值，其中，dBc是以dB為單位的該頻率處功率與總功率的比值。- -個振蕩器在某一偏移頻率處的相位噪聲界說為在該頻率處1Hz帶寬內(nèi)的信號功率與信號的總功率比值。 </p> <p> 相位差 </p> <p> 兩個頻率相同的溝通電相位的差叫做相位差，或許叫做相差。這兩個頻率相同的溝通電，可所以兩個溝通電流，可所以兩個溝通電壓，可所以兩個溝通電動勢，也可所以這三種量中的任何兩個。 </p> <p> 例如研究加在電路上的溝通電壓和經(jīng)過這個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分，溝通電流也等于零，溝通電壓變到比較大值的時分，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。
