FFT頻譜分析儀ZET 032描述
ZET-032多功能FFT頻譜分析儀旨在測量聲學和振動聲學信號的頻譜成分參數，并生成具有規范計量特性的電信號。
FFT頻譜分析儀ZET 032可以獨立使用，也可以在自動化系統和技術過程控制系統框架內用于科學研究目的。ZET 032系列模型的工作原理基于并行（同時）分析信號譜。這些儀器體積緊湊，可以在緊湊的實驗室環境中使用，也可以作為便攜式測量儀器使用。
當與ZETLAB ANALIZ軟件一起使用時，FFT頻譜分析儀可以解決以下任務：
實時模式下的信號分析，以及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；
- 窄帶頻譜分析；
- 交流和直流電壓測量；
- 電信號頻率測量；
- 正弦信號和直流信號的生成；
- 信號錄制（將已注冊信號的數字化值保存到設備的集成存儲器中）
測量結果的信息以用戶友好的格式顯示在外部儀器上。
集成的電荷放大器允許連接各種測量傳感器，因此可以實現各種附加功能，而無需使用額外的儀器。
