Hello, I am an Ettus newbie. We have an application that requires us to synchronize multiple B205 mini radios (RX side) using the PPS in signal. In the FPGA, the pps_in is reclocked into the radio clock domain. What we notice is that when we monitor this PPS signal (reclocked in radio clock

Hello all, I'm recording RF signal at 1.5 GHz using usrp2 with wbx daughterboard of fixed BW of 40 MHz; since I'm interested to capture the whole BW, I set the over-the-wire format to sc8 to be able to have 50 MSps rate; as example rx_samples_to_file suggests, there is no "byte" or "char"

Hello, I have built and installed gnuradio and uhd from the build-gnuradio script and I was able to run example gnuradio codes(nfm_rx.py) using usrp b200mini through command line. uhd_find_devices and usrp_probe shows the correct version but the GNURadio Companion does not detect the device.

[USRP-users] What is a burst?

2018-06-22 Thread Fabian Schwartau via USRP-users
Hi everyone, short question: What is a burst in UHD? I am talking about the flags start_of_burst and end_of_burst you get from revc in the meta data. I am using the STREM_MODE_NUM_SAMPS_AND_DONE mode and I thought that this is a burst. However, I displayed the two flags for each recv I

Hi Darek, I thought I solved this issue but it came up again. From time to time I get the late command error. I get it when calling the revc method for the receive stream. In that moment there is no data returned from the call (return value is 0). I get these results a couple of times and

Hello Dr Henarejos, Currently an RFNoC only flowgraph is not fully supported. What is missing is the issuing of the commands to start streaming and a mechanism to handle timestamps. Some modifications are needed to make these work. Nick Foster has done a write up on a few different ways of

Dear all, I am playing with RFNoC on a USRP X300. I built a custom RFNoC FPGA image with the blocks that I need successfully and everything goes smooth. However, if I want to use a flowgraph with only RFNoC blocks (RFNoC Radio RX --> DmaFIFO --> RFNoC Radio TX), it does not work. The USRP
