VK7012 USB 16-bit data acquisition card
VK7012 is a USB type low speed 16-bit data acquisition card developed by Shenzhen Vkinging Electronics Co., Ltd. The VK7012 acquisition card supports 4-channels of synchronous acquisition, high precision and high linearity 16-bit ADC, maximum 40kps, precision pre gain, and other features. The VK7012 USB uses multiple high-precision 16-bit ADC units and a front-end differential amplifier module developed in cooperation with our company for many years, making this product have the advantages of high speed, high resolution, high accuracy, ultra-low noise, high common mode rejection ratio, wide measurement range, low temperature drift, and is suitable for various occasions of precision acquisition.
Applications
*Weak signal measurement collection *Multi-channel signal synchronization collection
*High resolution signal measurement *High impedance differential signal measurement

Power status indicator (beside USB interface)
Acquisition status indicator (red and blue two-in-one LED):
1. Red and blue LED lights are out: normal collection is under way.
2. Blue light flashing constantly: indicates the stopped state of sampling, waiting for new command to start sampling again, standby state.
3. The red light will flicker: if there is data overflow or data error during the collection process.
4. The red light is always on: it means the data cannot be sent out, or the USB fails.
Collection card software description
The VK7012 USB data acquisition card can work in common operating systems such as WIN11/Win10/WIN7, LINUX, and provides a dynamic link library called by common programming languages such as Python, VB, VC, C #, C++Builder, VB, Delphi, Labview/Labwindows, and Matlab. The programming function interface is simple and easy to use, and it is easy to write applications. It provides routines such as Python, VB, VC, C#, C++Builder, VB, Delphi, Labview/Labwindows, and Matlab.
