VK702N 8-channel Ethernet 24-bit data acquisition card

                                                                                           VK702N Ethernet capture card  

    VK702N is an Ethernet type high-speed 24-bit data acquisition card. It features true differential input, 8-channel synchronous acquisition, sampling accuracy of up to 24-bit, 50 ksps sampling rate, and 16 times precision pre gain. Using multiple high-precision 24-bit ADC units, this product has the advantages of high-speed, high-resolution, high-precision, ultra-low noise, high common mode rejection ratio, wide measurement range, low temperature drift, and is suitable for various occasions of precision high-speed acquisition.

Applications

*Weak signal measurement collection            *Low noise data collection
*Ethernet networking measurement system   *High-impedance differential signal measurement
