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。這兩個頻率相同的交流電，可以是兩個交流電流，可以是兩個交流電壓，可以是兩個交流電動勢，也可以是這三種量中的任何兩個。例如研究加在電路上的交流電壓和通過這個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候，交流電流也等于零，交流電壓變到比較大值的時候，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RETS-100L相位差測量儀性價比高測試誤區(qū)：軸角度不是吸收軸角度。</p><div

相位差測試儀是工業(yè)領(lǐng)域中是常常用到的一般測量東西，比如在電力系統(tǒng)中電網(wǎng)并網(wǎng)合閘時，需求兩電網(wǎng)的電信號相同,這就需求準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討網(wǎng)絡(luò)、系統(tǒng)的頻率特性中具備重要意義。相位測量的方法許多，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，我們規(guī)劃了-種數(shù)字相位差測量儀,完成了兩列信號相位差的自動測量及數(shù)顯。近年來，跟著科學技術(shù)的迅速開展，許多測量儀逐步向“智能儀器”和“自動測試系統(tǒng)”開展，這使得儀器的運用比較簡單,功能越越多。
