Vescent qNimble Quarto Data Acquisition and Control Platform

Quarto - A Digital Brain for the Analog World™ 

The qNimble Quarto is a multi-function data acquisition platform that is easy to use but incredibly powerful. Low latency, 1 MSPS, 16 bit-ADCs and DACs are directly accessible with a blazing fast 500 MHz CPU dedicated to running your code. The CPU can read or write analog signals in just a few clock cycles ~1µs of latency. The Quarto is Arduino-compatible, so you can program it in the Arduino IDE or your favorite C/C++ environment. You can build a 100kHz bandwidth PID servo control system or custom digital filters with just a few lines of code.

How does the qNimble Quarto work?

The Quarto combines four high-speed, low-latency 16-bit DACs and ADCs with a powerful CPU and an FPGA. The FPGA handles all the communication with the DAC and ADC and we created InstraWrite™ to enable the CPU to read from or write to the FPGA immediately. Communication with the ADC and DAC never slows down the CPU. The entire signal chain is designed for low latency (~1μs) to support high-bandwidth servoing and filtering so you can respond to your data quickly. With hardware support for floating point math, you can do advanced math calculations on your data in real-time.
