GY-DAQA-2510 is a high-performance DAS dedicated data acquisition card, with dual-channel 1GSps synchronous trigger sampling, and comes with AWG function, which can generate 2-channel swept signal output for chirp pulse modulation.
The balanced photodetector contains two photodiodes and a low-noise transimpedance amplifier, in which the two photodiodes are matched to each other for excellent common mode rejection ratio
BPD570 Series Photodetectors Based on 2 high-performance APD photodetectors with consistent performance, adjustable M-factor, ultra-high common-mode rejection ratio of 30db and low noise.
