Hello, we do that at Nançay radio telescope with instrument WIBAR: two ADC 1.1GHz, downloaded via two 10Gb fibers. This is used to iteratively test RFI reduction strategies, taking the same waveform as input. Starting five years ago, we needed several disks in RAID0, feeded in two PCs per channel, using a 10Gb switch. However, to know what you get at last, you need to tag your blocks in FPGA. It turns out that in any configuration you loose sporadiquely some blocs depending on LINUX events (somebody login in for example). You may reduce these unfortunate events by compiling tuned kernel. It needs some skill. The loss at those input rate fails down to 10^7, which we find acceptable Regards Jean Borsenberger Le Mercredi, Mars 08, 2023 09:26 CET, Indrajit Barve <[email protected]> a écrit: Dear Wang, I use ROACH 1 with iADC. Block library's may be different. Logic you can use it by replacing the ADC block with your ADC library and 10 GBe library.

And do you have a description of the model？ The model is not complete after I opened it.

Hi CASPER， I built the FX correlator using ROACH2 and GPU server. Now there is a problem, I want to save the raw data that the ADC board outputs. I don't know how to do that. Has anyone thought about this problem or has a way to save ADC output data? I would appreciate a lot if you could reply me!
