    VK701WSD is a WIFI wireless data acquisition card with 4-channels of true differential input, 24-bit resolution, a maximum sampling rate of 400ksps, support for offline SD storage, and precise pre-gain amplification. This product uses multiple high-precision 24-bit ADC units and the pre-differential amplifier module developed by our company for many years, making this product have high speed, high resolution, high precision, ultra-low noise, high rejection ratio, and measurement range. The advantages of wide and low temperature drift are suitable for various occasions of precise and high-rate acquisition.

Applications
 

*Weak signal measurement collection       *Offline data collection and storage
*Multi-card network data collection          *High resolution signal measurement
