VK7022 USB 16-bit data acquisition card
VK7022 is a USB high speed data acquisition card, featuring USB port photoelectric isolation, 8-channel true differential input, 16-bit resolution,maximum sampling rate of each channel 5KSPS, 8-channel 40Ksps, and precision pre-gain amplification.The product adopts a number of high-precision 16-bit ADC units and the pre-differential amplifier module developed by the company over the years, so that the product has the advantages of high speed, high resolution, high precision, ultra-low noise, high suppression ratio, wide measuring range and low temperature bleaching. It is suitable for various occasions of precise and high-speed acquisition.
Applications
*USB data collection *Multi-channel signal synchronization collection
*High resolution signal measurement *Signal trigger acquisition system

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.
