I am interested in using Pynq to learn/teach about developing FPGA DSP content (filters, modems, etc) for use with a SDR (software defined radio).
I have had a look at the supported boards and see ZCU-111 has excellent support for this but is very expensive ($8999 list, then you need to buy RF front end parts).
So, do any of the other boards have a high speed ADC/DAC connected to the PL?
And/or could one interface the PL on one of these boards to the commonly available USB-attached experimenter’s SDRs such as HackRF1, RTL-SDR, etc?
Or interface to Ethernet attached radios such as USRP (which are also on the expensive side unfortunately)?
Or is the most feasible method to attach the SDR to PS’s USB/Ethernet then use DMA and ring buffers to move data into and out of the PL? Seems this would add a lot of latency.
