Features
The optical attenuation and optical power output can be set quickly and accurately, and the optical power control stabilization time is ≤ 200 ms.
The multi-channel attenuator is set up at the same time, and multiple ports are measured at the same time, saving a lot of measurement time;
Built-in high-precision optical power meter ensures the stability and accuracy of power monitoring;
Simple operation, intuitive graphical user interface, preview of multi-channel data at the same time, and the test status is clear at a glance.
Small in size and compact in structure, two 4-channel devices are cascaded and can be identified as an 8-channel device for use.
