Re: [USRP-users] Streaming 8-bit (sc8) samples from RFNoC

I seem to recall that the 8-bit OTW format isn't implemented for RFNoC yet... I could use that too. On Mon, Mar 19, 2018 at 9:07 PM Adam Parower via USRP-users < usrp-users@lists.ettus.com> wrote: > Hello everyone, > > > I am trying to figure out how to receive complex 8-bit integer samples > fro

Hi Michael, Here is the public repo with the custom block source code: https://st...@code.oceanit.com/stran/gr-per.git . The block is called Ansect Per ('Ansect' is the name of my own project I am using it for and 'per' stands for packet error rate). The source code is under /lib/ansect_per_i

Hi Nate, Now after I did those changes it looks much better. However, seems still there is kind of mirrored spectrum on fosphor plot. I just did simple test with transmitting signal from Zigbee sensor device. Seems signal is mirrored on plot. I will check more tomorrow, and will let you know. T

2018-03-19 Thread Adam Parower via USRP-users
Hello everyone, I am trying to figure out how to receive complex 8-bit integer samples from a USRP containing a custom RFNoC flowgraph. If I didn't require RFNoC and could use the legacy UHD C++ API instead, this would be trivial; I would simply set both the host format and on-the-wire format

Hi Tarik, If you press "F6" instead of the "Run" button, it will bypass this warning and run the flowgraph. Regards, Nate Temple On Mon, Mar 19, 2018 at 8:59 AM, Tarik Kazaz via USRP-users < usrp-users@lists.ettus.com> wrote: > Hi All, > > > I am using USRP X310 with UBX-160MHz. I tried to run

Hi All, I am using USRP X310 with UBX-160MHz. I tried to run RFNoC fosphor demo, however I am getting errors related to connection of RFNoC:Radio to RFNoC: DDC and to RFNoC:Window (Source IO size "8" does not match sink IO size "8192"). I found this discussion on mailing list (from 2016) https

Hi, I am building an OFDM receiver on X310 using RFNoC. When I run the rfnoc_ofdm.grc example in the gr-ettus examples, I met the "timeout on chan 0" failure once I enable the RFNoC: OFDM Sync block. The other blocks seems to be fine, say the FIFO and FFT block, but if enable the Sync block, the f
