The USB data acquisition card is a high-efficiency multi-function data acquisition card with USB interface. It has 8 channels of differential 16-bit resolution and high-speed synchronous analog signal acquisition (the highest synchronous acquisition rate is 200KSPS, and synchronous acquisition means each channel Both are 200KSPS), 2 channels of 12-bit analog signal output (only single low-speed output mode), 16 channels of digital signal one-way input and output, 2 channels of 32-bit PWM and other precision measurement inputs, 2 channels of 32-bit PWM or single pulse output . AD supports internal and external time, internal and external triggers.
Features：
- 8-channel differential (Differential) analog input, synchronous acquisition
- 16-bit resolution 200KHZ AD
- Signal dynamic range: ±10V / ±5V
- 2 channels 12-bit DA, output 0-10V
- Digital quantity: 16 in (DIO-DI15)/16 out (DOO-DO15)/ (5V -TTL level)
- 2 channels of 32-bit PWM measurement input, measurement time: 48MHz, equal precision measurement, measurement error is a reference time of 48MHz, 2 channels of PWM measurement input 0-1 are shared with DI2-DI3 respectively
- AD conversion mode has 16-channel synchronous conversion mode
- AD conversion time: internal and external trigger, trigger level 5V, shared with digital input channel DI1, external time can be selected to rise or fall
