Data acquisition card for distributed fiber optic vibration monitoring system
2023-06-04 08:05:02
Introduction
The PICE-6820-DAQ is a high-speed data acquisition card customized for distributed fiber optic vibration monitoring systems.
The DVS data acquisition card has a trigger output function, which is the same source as the sampling clock and can effectively solve the problem of signal jitter. In addition, the DVS data acquisition card comes with a differential demodulation algorithm, so users can choose to use it, or choose the original signal to process it by themselves.
Many general-purpose data acquisition card without pulse output function, then the user needs to do a separate trigger pulse to aom, in addition to this pulse to the acquisition card to do external trigger, if the clock signal is not given to the acquisition card, very easy to cause jitter.
Features

How to connect to a DVS system
The trigger output interface of the DAQ is connected to the AOM driver, which provides the TTL signal.The DAQ has 2 acquisition channels that connect to the detector output port of the DVS system.
How to connect to the computer
The data acquisition card uses PCIe x8 interface. Since PCIe x16 is compatible with PCIe x8 interface, the DAQ data card of DVS can be plugged into either PCIe x8 or PCIe x16 slot.
How to collect data
This DVS DAQ capture card can only run on Windows platform, we provide dynamic connection library (.dll file), you can call the API interface exposed by .dll file through programming language.
