250M Gigabit network port DTS temperature measurement and acquisition card

Product Overview

The FT-VC-DTS-ETH-250M-2 network interface high-speed acquisition card belongs to the series of high-speed DAQ acquisition cards specifically designed for weak signal acquisition, developed for the distributed Raman DTS optical temperature measurement system, and also compatible with the acquisition of weak echo signals from aerosol lidar. It features dual channels of 12-bit ADC, supporting software switching of 100MSps/250MSps sampling rates, suitable for projects with different distances and spatial resolutions; it includes a hardware accumulation averaging algorithm, capable of up to 65536 accumulations to amplify weak Raman signals, significantly reducing noise; it supports TTL external triggering for optical path synchronization and low-latency transmission via Gigabit network interface UDP; the board is available in two versions: bare board FT-VC-DTS-ETH-250M-2 and with a casing FT-VC-DTS-ETH-250M-2A. It is small in size, low in power consumption at 12V, and is the preferred acquisition hardware for DTS equipment manufacturers as OEM, for university Raman temperature measurement research, and for aerosol radar development.
