USB3131A 16Bit 100Ksps USB Multifunctional Data Acquisition Module 16-Channel Programmable DIO Analog Acquisition

Description:
- USB3131A/2A/3A/4A/5A/6A is a USB multifunctional data acquisition card that uses unique USB Stream transmission technology (similar to DMA) to ensure the stability and real-time transmission of USB data at high speed.
- Features include: 16 channel analog signal acquisition; 2-channel analog synchronous output; 16 programmable DIOs; 2-channel multifunctional counters.
- The system diagram of USB3131A2A/3A/4A/5A/6A mainly consists of ADC module, DAC module, PFI multiplexing function control module, digital input/output module, FPGA control module, USB device controller, etc.
- The ADC module can realize the acquisition of 16 channel RSE/NRSE or 8 channel DIFF. The input front-end uses analog switches to switch input channels, supporting on-demand single point sampling, finite point sampling, and continuous sampling.
- The DAC module can achieve 2-channel signal synchronous output, with an output range of 10V. Supports on-demand single point sampling, finite point sampling, and continuous sampling.
- The digital input/output module includes a PFI multiplexing function control module (providing 8 configurable digital input/output and multifunctional I/O) and 16 DIO modules.
- USB3131A/2A/3A/4A/5A/6A counting includes PWM pulse output edge counting, frequency measurement, cycle measurement, half cycle measurement, pulse measurement, pulse width measurement, double-sided edge interval measurement, and encoder position measurement.
