FFT频谱分析仪ZET 032描述
ZET-032多功能FFT频谱分析仪旨在测量声学和振动声学信号的频谱成分参数，并生成具有规范计量特性的电信号。
FFT频谱分析仪ZET 032可以独立使用，也可以在自动化系统和技术过程控制系统框架内用于科学研究目的。ZET 032系列模型的工作原理基于并行（同时）分析信号谱。这些仪器体积紧凑，可以在紧凑的实验室环境中使用，也可以作为便携式测量仪器使用。
当与ZETLAB ANALIZ软件一起使用时，FFT频谱分析仪可以解决以下任务：
实时模式下的信号分析，以及先前记录信号的分析；
- 基于并行数字滤波器的八度和1/3八度分析；
- 窄带频谱分析；
- 交流和直流电压测量；
- 电信号频率测量；
- 正弦信号和直流信号的生成；
- 信号录制（将已注册信号的数字化值保存到设备的集成存储器中）
测量结果的信息以用户友好的格式显示在外部仪器上。
集成的电荷放大器允许连接各种测量传感器，因此可以实现各种附加功能，而无需使用额外的仪器。
