Hi Group,
Here is an interesting SDR project for someone. People have discovered that some of the inexpensive (<$500) Siglent scopes contain a Xilinx Zynq FPGA. They have hacked the scope and can run new FPGA gateware:
These scopes have two 8-bit 1GHz ADC. The ADCs can be shared for 4 8-bit 500MHz inputs. Although only 8-bits, processing gains given the high sampling rates should improve overall dynamic range. The scopes also have ethernet. This could make an interesting 4-channel coherent SDR receiver. The zynq processor also has an ARM core, similar to the red pitaya. Imagine a scope which can be used as a scope, but which you can at times load an alternate gateware to make it a SDR!
