While technically perhaps possible.... The XC7X010 Zynq FPGA used on the ADALM-PLUTO is going to be limiting for any Casper signal processing work as it has a total of 80 multipliers and only 28,000 LUTs, that's really tiny for doing anything more than a simple polyphase decimator and a streaming I/Q output, which is basically what they give you out of the box from Analog Devices.

See https://github.com/WVURAIL/lightwork/blob/master/memos/LightWorkMemo032-PailOfMilkyWay-r5.pdf (All parts cost about $500 US, including the Raspberry Pi 400). The associated python code is there as well. This is not really a “CASPER” project as this uses Gnuradio code. Glen, FYI I believe that the CASPER software could be ported to the Analog Devices Pluto SDR, but this has not yet been accomplished, I believe. This device is supported by Gnuradio. https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm-pluto.html#eb-buy It would be great if someone could port the CASPER tools to this device. > On Aug 16, 2023, at 11:20 AM, 'Hawkins, David W (US 334B)' via > [email protected] <[email protected]> wrote: > > Hi Colm, >>> I am looking for components that easy to interface with via python > In that case, I would recommend investing in: > https://www.realdigital.org/hardware/rfsoc-4x2 > Students can still learn about RF mixers, power amplifiers, and LNAs, and > they would use the RFSoC board as a high-end signal generator and data > acquisition system. > The Red Pitaya is another option, but it has lower bandwidth DACs and ADCs. > Regards, > Dave > From: [email protected] <[email protected]> On Behalf > Of Colm Bracken > Sent: Wednesday, August 16, 2023 3:25 AM > To: [email protected] > Subject: [EXTERNAL] [casper] Advice for radio astronomy components > student project Dear Casper, I hope you are all well today! > I am hoping some of you might have some advice/ideas for easily-intefaceable > RF components. > I want to purchase signal generators (~100 MHz), and a range of local > oscillators for a student project. > Ideally I am looking for components that easy to interface with via python > (or Matlab if necessary).
