DAM2421 High Speed Data Acquisition Module
2014/6/4 17:02:31 Author：Admin Hits：2220次
Description
DAM2421 Series high speed data acquisition module utilizes the hardware real-time accumulating average technology to promote the weak signal. The signal to noise ratio of original signal is effectively improved after the 60000 accumulating. It can be flexibly applied to kinds of OTDR sensing system.
Features
Ø High sampling frequency, reaching 200M sps
Ø Built-in accumulative algorithm, improving the SNR
ØSupporting the synchronous pulse signal output
