VK701N-SD four-channel Ethernet 24-bit data acquisition card

VK701N-SD Ethernet capture card  

    VK701N-SD is an Ethernet type (LAN) 24-bit data acquisition card. The VK701N-SD Ethernet acquisition card features true differential input, 4-channel synchronous acquisition, sampling accuracy up to 24 bits, a maximum sampling rate of 400 ksps, adjustable pre gain units, and offline data storage. The VK701N-SD Ethernet data acquisition card uses multiple high-precision 24-bit ADC units and input filter units, 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.
