Well, yes I do want to do that. It's a test of data transfer capabilities of the PC in preparation for use with an X410 in the future (but I don't have an X410 yet).
The other reason for over sampling the band is that in detecting a pulse of RF signal, the precise start time is very important in our application so that the higher sample rate affords better resolution in that regard. The X310 has two 10GbE interfaces, is there not an approved way of using them in this manner? What if I had 2 x TwinRx and wanted to get 100MSPS from all four of them? kind regards JP -----Original Message----- From: Marcus Müller <marcus.muel...@ettus.com> Sent: Wednesday, 2 March 2022 21:16 To: usrp-users@lists.ettus.com Subject: [USRP-users] Re: single flow utilising multiple receivers with high sample rate WARNING: This message has originated from an untrusted source.
