This is a data acquisition card for distributed fiber optic vibration monitoring system (DVS) with built-in TTL pulse signal trigger output function to provide signal to the AOM driver, saving extra signal generator (AWG) and reducing the integration difficulty and complexity of the system.
The module is internally integrated with a DVS optical path for distributed fiber vibration and a data acquisition card with Gigabit Ethernet interface output, which only needs to be paired with a PC to form a DVS system.
