型數(shù)字綜合振蕩器配套可組成繼電保護(hù)高頻通道自動測試儀，完成同步測量、阻抗測量、雜音測量、高頻通道近端同步、遠(yuǎn)程自動對測等功能。是一種新型的全鍵盤操作、全中文界面、高清晰LCD 顯示的全數(shù)字化智能儀表。數(shù)字綜合電平表和數(shù)字綜合振蕩器可獨(dú)立使用，也可配套組成繼電保護(hù)高頻通道測試儀。適用于300 路以下的平衡和同軸電纜FDM 系統(tǒng)以及無線鏈路和衛(wèi)星系統(tǒng)的基帶電平測量，由于振蕩器的高電平輸出（＋20dB）和電平表的高電平輸入（＋50dB）測量，儀器特別適用于電力載波和電力線保護(hù)設(shè)備的測試。例如高電壓輸電線路、變電站等場所的電力線載波通道進(jìn)行衰減、串雜音等高頻參數(shù)測試，以及電力通信結(jié)合設(shè)備高頻阻波器、結(jié)合濾波器、高頻電纜的開通維護(hù)測試。<br
