1GSps dual-channel high-speed data acquisition card
[DAQ] 2026-01-21 02:15:33
The GY-DAQ-2510D acquisition card employs dual-channel 14-bit high-speed ADCs, featuring dual-channel 1GSps synchronous trigger sampling and supporting DAS data acquisition over distances exceeding 100km. With built-in phase demodulation algorithms, it can directly upload amplitude-phase demodulated data.
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.
Dual Port APD Receiver Module For Raman DTS
