ERM-202 将低噪声电路与高分辨率步进电机相结合，可实现 50 dB 的 PER 动态范围和 0.06° 的角度分辨率。它可同时测量 DUT 的 PER、输出功率和轴角。此外，双通道版本可测量具有两个保偏 （PM） 输出的设备的功率比，例如 Y 分支光纤陀螺仪 IOC、PM 耦合器 （PMC） 或偏振分束器 （PBS）

Product Description:
The ERM-202 combines a low-noise circuit with a high-resolution stepping motor, achieving a PER dynamic range of 50 dB and an angular resolution of 0.06°. It can simultaneously measure the PER, output power and shaft Angle of the DUT. In addition, the dual-channel version can measure the power ratio of devices with two polarizing (PM) outputs, such as Y-branch fiber gyroscope IOC, PM coupler (PMC), or polarization beam splitter (PBS).
Product Features:
The measurement range of PER is greater than 50 dB
Angular resolution: 0.06°
Simultaneous PER and power ratio measurements (dual-channel)
