[USRP-users] What is the proper way to design an RFNOC module that takes sc16 and outputs sc8?

2023-06-26 Thread Vermeulen, Bas (Consultant) via USRP-users
Hi, We're working on an RFNOC module that receives sc16 from the radio, and down-scales it to sc8. Our current module does this by doing the down-scaling for 2000 samples, and then divides the data in the chdr header by two. This doesn't work properly for use with srsRAN; what is the best way t

[USRP-users] TwinRx in coherent setup

2023-06-26 Thread Carlo Venier
Good evening to everybody, I am trying to use an X300 with two TwinRX in a coherent setup. After synchronization, in the case of fixed frequency operation (no re-tuning) the phase differences among the channels are constant and they remain constant over time. However, if I re-tune the TwinRx on th

Is there a chance that the issue is caused by the timed commands occurring prior to the "set_rx_rate" command (as indicated in the code provided in the issue tracker)? I don't know how the DDC responds to timed commands prior to knowing its output rate. Rob On Mon, Jun 26, 2023 at 11:22 AM Marcus

Thanks Rob. Actually, prior to tune the TwinRx I set the sampling rate. Il lun 26 giu 2023, 17:33 Rob Kossler via USRP-users < usrp-users@lists.ettus.com> ha scritto: > Is there a chance that the issue is caused by the timed commands occurring > prior to the "set_rx_rate" command (as indicated in

I have updated the rfconverter_libiio file in the base of Matlab. Now I can see the variation in signal power in the spectrum analyzer. However, in the receiver, the problem is still the same. On Mon, Jun 26, 2023 at 8:36 PM Marcus D. Leech wrote: > On 26/06/2023 09:32, Arhum Ahmad wrote: > > Th
