100MSps high speed DAQ card for DVS
[DAQ] 2025-04-03 13:43:15
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.
Enhanced DAS hardware all-in-one TCP protocol direct vibration signal output
[DVS Module] 2025-08-05 00:17:30
Enhanced DAS all-in-one is capable of real-time demodulation of the phase of the entire fiber optic cable, TCP protocol output of vibration signals, and coherent attenuation suppression, enabling the output of purer signals than general-purpose DAS all-in-one.
