ERM-202 Polarization Extinction Ratio Meter
⠀⠀⠀⠀⠀⠀⠀⠀⠀
The ERM-202 is a rotating-polarizer polarization extinction ratio meter. It is available in single or dual channel versions.
PRODUCT DESCRIPTION
The ERM-202 combines low noise circuitry with a high resolution stepper motor to achieve a PER dynamic range of 50 dB and angle resolution of 0.06°. It simultaneously measures PER, output power, and axis angle of the DUT. In addition, the dual channel version measures the power ratio of a device with two polarization maintaining (PM) outputs, such as a Y-branch fiber gyro IOC, PM coupler (PMC), or polarization beam splitter (PBS).
Key Features
- PER measurement range >50 dB
- Angle resolution 0.06°
- Simultaneous PER and power ratio measurement (dual channel)
