Moku:Lab波特分析仪(扫频仪)可用于使用10 mHz - 120 MHz扫频正弦波输出信号测量系统传递函数的振幅和相位。该功能可用于测量谐振器件的共振频率与相位、被测件的幅频响应曲线、被测件的传递函数及被测件在每一个频率点下的振幅/相位与频率的变化关系。
特色
1、线性或对数扫频正弦输出
2、同时探测两个系统,或一个系统上的两个点
3、用于在获取响应函数时对其进行加、减、乘或除法运算的数学通道
4、查看交互式波特图上的幅值和相位
5、使用光标和标记来测量图上的准确值
6、精确调整稳定时间(settling time)和平均时间(averaging time)以适用被测设备
7、保存校准曲线以比较系统或补偿电缆延迟
8、轻松保存数据并上传到云端
