Overview
The system integrated light decayer is used primarily for the reduction of wavelength signal power; the internal power meter is used to monitor the power of each wave long decay; it is also applied to the high frequency condition decay test; the decay value is subject to low frequency interference; the model model of multiple models is small (compatiblely tested light sources such as LED, Vcsel, FP); the system is controlled by advanced high performance cores; functionally functional; and is of good linearness and low penetration loss and loss. With upper-space functionality; simultaneous display of measurements using 320*240 colour LCD. There are three working models for single tape monitoring decayers; (1) \tATT mode; and setting fixed decay values. (2) \tAPC mode; setting output power values; automatic fine-tuning with decay. (3) \tATC smart model; setting precise fixed decay values; automatic fine-tuning with decay. APC and ATC models achieve non-continuing tests for PDF, WDL and TDL; significantly reduce the impact of the use of environmental, photogenic, etc. on decay accuracy
