style="text-indent:25px">在離中心頻率一定合理距離的偏移頻率處，邊帶功率滾降到1/fm，fm是該頻率偏離中心頻率的差值。相位噪聲通常定義為在某一給定偏移頻率處的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。一個(gè)振蕩器在某一偏移頻率處的相位噪聲定義為在該頻率處1Hz帶寬內(nèi)的信號功率與信號的總功率比值。相位差兩個(gè)頻率相同的交流電相位的差叫做相位差，或者叫做相差。這兩個(gè)頻率相同的交流電，可以是兩個(gè)交流電流，可以是兩個(gè)交流電壓，可以是兩個(gè)交流電動(dòng)勢，也可以是這三種量中的任何兩個(gè)。例如研究加在電路上的交流電壓和通過這個(gè)電路的交流電流的相位差。如果電路是純電阻，那么交流電壓和交流電流的相位差等于零。也就是說交流電壓等于零的時(shí)候，交流電流也等于零，交流電壓變到比較大值的時(shí)候，交流電流也變到比較大值。這種情況叫做同相位，或者叫做同相。如果電路含有電感和電容，交流電壓和交流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，或者電壓超前于電流，或者電流超前于電壓。相位測量當(dāng)今，相位的測量需求日益增長。高精度測距大多采用的是激光相位式測距。相位式測距是通過測量連續(xù)的幅度調(diào)制信號在待測距離上往返傳播所產(chǎn)生的相位延遲。江蘇日文王子相位差測量儀售后保障測量波段：550nm單波段，上料方式：手動(dòng)上料。</p><div

style="text-indent:25px">來間接的測定信號傳播的時(shí)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(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兩個(gè)同頻率信號之間相位差的測量。**常見的是對網(wǎng)絡(luò)輸入與輸出信號的相位差，即網(wǎng)絡(luò)相移的測量。</p><p style="text-indent:25px">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(jì)了一種數(shù)字相位差測量儀，實(shí)現(xiàn)了兩列信號相位差的自動(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，功能越越多?？伤菰葱?可提供計(jì)量檢測報(bào)告。</p><div
