deband)。從圖2中能夠看出，在離中心頻率-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。相位噪聲通常界說為在某-給定偏移頻率處的dBc/Hz值，其間，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。江蘇RETS-100L相位差測量儀售后保障公司主要的經(jīng)營范圍為光電材料、電子科技、軟件科技領域內(nèi)的技術開發(fā)。</p><div

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">相位常應用在科學領域，如數(shù)學、物理學等。例如：在函數(shù)y=Acos(ωx+φ)中，ωx+φ稱為相位。在astrolog32中點擊ALTIFT+A可以顯示相位設定菜單。在交流電中，相位是反映交流電任何時刻的狀態(tài)的物理量。交流電的大小和方向是隨時間變化的。比如正弦交流電流，它的公式是i=Isin2πft。i是交流電流的瞬時值，I是交流電流的比較大值，f是交流電的頻率，t是時間。隨著時間的推移，交流電流可以從零變到比較大值，從** 大值變到零，又從零變到負的** 大值，從負的比較大值變到零。在三角函數(shù)中2πft相當于弧度，它反映了交流電任何時刻所處的狀態(tài)，是在增大還是在減小，是正的還是負的等等。因此把2πft叫做相位，或者叫做相。測量波段可升級為380nm~780nm。</p><div style="width:100%;text-align: center;"><img
