Ok. I couldn't seem to duplicate with the stock "rx_samples_to_file", but with the following minor mods, I see some of the bad behavior. This sure looks like a UHD bug to me. I simply added timed commands around the set_rx_freq() function (see snippet below as well as attached source code). Is

Re: [USRP-users] x310/ubx multi_usrp->set_rx_freq() issues

I do see in the documentation that the tune result "target_rf_freq" will match the tune request "rf_freq", which it does in my example below. So, I suppose the output shown is as expected for my request. Unfortunately, this doesn't solve my problem of the actual spectrum being wrong. I may have t

Hi, I am seeing some strange (and unrepeatable) behavior with an X310/UBX-160 and the multi_usrp->set_rx_freq() function. I call this function with a tune_request that I create with a desired target frequency & lo_offset. The output below shows a "pp_string" of the request and the result (for the

[USRP-users] E312 RFNOC time update

Dear All, For E312 RFNOC, I have a question about updating time for both tx and rx chain. I would like to send and receive pulses at a certain time simultaneously(As long as they happen at the same time, it is fine). I have already set this up by playing with vita time in FPGA and time_spec in

Hi, I am using rx_multisamples.cpp to receive data from USRP. Whenever I am getting an error instead of giving error my application is getting aborted. Is there a way to get error message rather than the application being aborted? Like if we don't have the LAN connection with the USRP, the app

[USRP-users] Pybombs has inconsistency in Versions from UHD and FPGA src

Hallo Ettus, We developed on 3.14.0-rc1 within a sandbox, installed over pybombs. Now we wanted to move to the final release of 3.14.0 and installed a new sandbox. We generated out of this sandbox also a standard FPGA-image and we get the error, that UHD has version 35, but the FPGA has the versio
