GNU Radio in a Direct-RF World
summary
Describes using quad‑channel converters like the 9081 that deliver 4 GS/s ADC and 12 GS/s DAC data over JESD204b links into FPGA carriers (ZCU102/VCU118) and shows hardware (FMC eval cards) running synchronized 16‑channel I/O. Practical tactics: use large onboard capture (Pluto has 512 MB onboard RAM and buffer tags), push channelizers/DDCs/NCOs into FPGA, or move event detection into silicon to achieve up to a 250x reduction in host bandwidth.
