Software Defined Instrumentation : FPGA SoC based products
To illustrate the place of FPGA SoC in the so called Software Defined Instrumentation world, we list a few products relying on this technology.
RedPitaya
RedPitaya has just released the Gen 2 of its STEMlab 125-14v (link) ! It is based on Xilinx Zynq 7010/7020 with ADC/DAC interfaced on board. Maximum sampling is 250 MSPS.
A webserver is instantiated in processing part so that the device can be remotely operated using web applications.

Moku:Go
Moku:Go is the most accessible product from Liquid Instruments (link).

Liquid Instruments has made tremendous efforts to develop a powerful and user friendly set of software defined instruments: PID, AWG, Oscilloscopes etc.
Liquid Instruments is not very explicit about the FPGA exact reference, but it is likely to be Zynq/Zynq UltraScale+, depending on the class of the Moku (Go/Lab/Pro).
