Hi Glen,
The ADRV9009 is an improved version of the AD9361/AD9363 used on the PlutoSDR. It uses JESD204C high-speed transceivers for the interface, and can be used with a number of FPGA development boards. But I do not know if anyone has a CASPER interface to it. This is why the RFSoC 4x2 boards may be the best solution to a lot of problems, as CASPER already has support for them 😊 For those who do not know, commercial entities can buy the boards for about $5k (versus half that for Universities).

I’m still looking for the low cost entry point to CASPER. Any alternatives appreciated. The Pluto does have a number of fantastic features, including two inputs and two outputs, so that returning (TXing) a version of input signals might be a great test. It has 50db of gain. A limited version of Gnuradio is supported in the ARM processor. Often the PlutoSDR devices actually contain dual core processors. My desire is actually event detection, that was implemented (long, long ago), on an iBoB, which detected short term events and flags data capture. I’d like to do this at 60 MHz bandwidth, but only capture a fraction of a second. Which is possible on the PlutoSDR, but not for much data.
