VK702USB 8-channel isolated 24-bit data acquisition card

VK702 USB 24-bit data acquisition card

    VK702 USB uses multiple high-precision 24-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, and low temperature drift. It is suitable for various occasions of precision high-speed acquisition.

Applications
 

*Weak signal measurement collection *Low noise data collection

*High resolution signal measurement *High impedance differential signal measurement
