Data Acquisition Card for Distributed Acoustic Fiber Sensing (DAS) with Pulse Output sends TTL pulses directly to the AOM driver, eliminating the need for an additional pulse generator and greatly reducing system complexity.
The UNL-C-F-M-C34-13-7-1-0-0 is a narrow linewidth 1550nm laser module from YB Photonics. It features an ultra-narrow linewidth (<3kHz) making it ideal for distributed fiber optic sensing systems(DVS/DAS) and wind radar.
DTS-ETH-250M-2 is a special data acquisition card for DTS of distributed fiber optic temperature measurement system, which adopts Gigabit Ethernet port for data transmission and built-in averaging function with very high signal-to-noise ratio. Each channel supports a maximum of 32768 points acquisition, averaging up to 65536 times, 250M sampling rate, spatial resolution of 0.4 meters.
The DAQ board, which can be set up to 1G sample rate and has built-in trigger output and input interfaces, can be used for applications such as DAS distributed acoustic sensing system with 200M AOM acquisition or LIDAR.
Introduces the configuration of the pulsed laser for DTS temperature sensing, including how to set the ACC and APC modes, the trigger method and the pulse width parameters.
