振动声学信号FFT频谱分析仪ZET 034的命名:
ZET 034多功能FFT频谱分析仪用于测量谱成分参数(存在于振动、声学和水声信号中),以及生成具有规范计量特性的电信号。
FFT频谱分析仪ZET 034可同时在独立模式下和用于科学研究目的的自动化和过程控制系统中使用。ZET 03X系列仪器的工作原理基于信号谱的并行(同步)分析。
当与ZETLAB ANALIZ软件一起使用时,FFT频谱分析仪可以实现以下功能:
- 实时模式下的信号分析和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;
- 进行窄带频谱分析;
- 测量交流和直流电压;
- 测量电信号频率;
- 生成正弦和直流电压信号;
- 录制信号(将数字化信号值保存到内存,然后记录到硬盘)。
测量参数的信息以用户友好的格式显示在外部设备上。
一体化解决方案是基于FFT频谱分析仪ZET 034。
