振動聲學信號FFT頻譜分析儀ZET 034的命名:

ZET 034多功能FFT頻譜分析儀用于測量譜成分參數(存在于振動、聲學和水聲信號中),以及生成具有規范計量特性的電信號。

FFT頻譜分析儀ZET 034可同時在獨立模式下和用于科學研究目的的自動化和過程控制系統中使用。ZET 03X系列儀器的工作原理基于信號譜的并行(同步)分析。

當與ZETLAB ANALIZ軟件一起使用時,FFT頻譜分析儀可以實現以下功能:

  • 實時模式下的信號分析和先前記錄信號的分析;
  • 基于并行數字濾波器的八度和1/3八度分析;
  • 進行窄帶頻譜分析;
  • 測量交流和直流電壓;
  • 測量電信號頻率;
  • 生成正弦和直流電壓信號;
  • 錄制信號(將數字化信號值保存到內存,然后記錄到硬盤)。

測量參數的信息以用戶友好的格式顯示在外部設備上。

一體化解決方案是基于FFT頻譜分析儀ZET 034。
