Re: [casper] ADCs in CASPER

Hi Dan, This is the first I’ve heard of a ~$2K RFSoC education board. I couldn’t find any information with a quick web search. Does it have a part number? Is information available from Xilinx, or is it a hush-hush thing? Regards, Ross > On Oct 26, 2020, at 11:32 AM, Dan Werthimer wrote:

Re: [casper] ADCs in CASPER

Hi all Thanks for all this feedback, it has been very useful and informative. At the moment we don't have a specific array in mind. At SARAO we are busy in the initial design stages of a new correlator with both the F- and X-Engines implemented on a GPU. We are hoping that the short software

Re: [casper] ADCs in CASPER

hi gareth, can you tell us a bit more about your project? sample rate? number of ADC bits? number of ADC's? ADC analog bandwidth ? then people might be able to provide better advice. some random thoughts: you probably know the SNAP board has a ZDOC connector on it, so the old CASPER ZDOC

Re: [casper] ADCs in CASPER

Hi Glen, The CASPER tools support the Red Pitaya -- https://www.redpitaya.com/Catalog/p57/stemlab-125-10-starter-kit?cat=c99 -- which is ~200 EUR. Somewhat similar in price to the Pluto but admittedly without the RF front end. This support was added in the last couple of years by our South

Re: [casper] ADCs in CASPER

Hello Casperites, I’ve been following quietly, since I’ve not built any useful Casper-like-devices since we built “Ruppi” a decade ago. It was a clone of the Green Bank Observatory’s Guppi pulsar device (now deceased I think). We did publish a few pulsar results using the NRAO 140ft. As

Re: [casper] ADCs in CASPER

Hi Gareth, Jack, Jonathon, Nima, and I have been discussing a low-cost board to serve the N>1000 space, w/ digitization at the antenna (2 ch; ≤ 500 GS/s; ≥ 12 bits; SOC; low power; 10 GbE out). Do the above parameters overlap what you'd like to see, and do you have a price point in mind?

[casper] ADCs in CASPER

Hi Casper Community Now that roach2 has been deprecated, I have been wondering where the CASPER community is heading in terms of future ADC work. As far as I can tell there are three options available: 1. SNAP boards - The SNAP boards seem to support the largest number of options 12 x 250
