[USRP-users] New E310 doesn't boot without console cable plugged in

Hi all, we have recently purchased 2 USRP E310 radios, P/N 156333H-D1L. Both of them are stuck with all LEDS on when switched on, unless I connect the USB serial console cable before switching on, then they boot normally. Both booted with the original SD-card, unmodified. If I connect the cons

Hi list, I have followed the application note https://kb.ettus.com/Software_Development_on_the_E3xx_USRP_-_Building_RFNoC_UHD_/_GNU_Radio_/_gr-ettus_from_Source to set up a cross compile environment for an E310 SDR. It works well, however I have not been able to get past chapter 7: Building a c

Re: [USRP-users] E310 LO offset problem

ced earlier that the default max_num_samps() value reported was 508 when stream_arg was not set. So only question left is why spp should be 508, not 512? If changing the bin size to 256, should spp be set to 252? Fra: USRP-users På vegne av Skorstad,Jørn via USRP-users Sendt: tirsdag 22. okto

[USRP-users] E310 LO offset problem

Hi list, I am writing a C++ software which will scan through a given frequency range and perform an fft. The software seems to do what it should, however something weird happens when using LO offset tuning. With the following settings all looks correct: Sample rate 6.4M - master clock 51.2M -

[USRP-users] E310 packet size

Hi all, Still trying to understand some parts of the USRP that probably are quite elementary. When using the function get_max_num_samps it always reports 508. Does this mean that the number of samples returned for any requested sample rate will be decimated down to 508? Any way to change max_nu

[USRP-users] E310 filter settings and LO lock question

Hi all, I am currently working on a project using a USRP E310 to output an FFT plot over a given frequency range (usually bigger than the possible sample rate). The program is written in C++ using the UHD library. Frequency range is achieved by changing the LO frequency regularly. The program
