Re: [USRP-users] Add an external clock to a USRP x310

Hi all, Marcus, Thanks for the answer, it was really useful. Now, I am trying to generate the 10Mhz signal using a vector signal generator, but the signal is nor really pure because the signal generator bandwidth is only 60MHz. Also, the Vpp of the signal is 1.4 V, is it correct? If someone can s

Hi Marcus, Thanks a lot! What GPSDO do you recommend? We need to buy one. Best regards, Alejandro 2018-04-06 16:00 GMT+02:00 Marcus D. Leech : > On 04/06/2018 08:29 AM, ALEJANDRO BLANCO PIZARRO wrote: > > Hi all, Marcus, > > Thanks for the answer, it was really useful. Now, I am trying to gener

[USRP-users] UHD rfnoc-devel version

Hi, The rfnoc-devel branch has now been updated to include fixes and requires Vivado 2017.4. I’ve always created the development environment with PyBOMBS and it seems as though this always pulls the latest version of UHD from the GitHub repository. Is there any way to pull the previous version o

Re: [USRP-users] Assistance In Stopping Python Script After Removing Ethernet Connection

Thanks for everyone’s assistance. I did not get a chance until now to update the situation… Basically, this is what I did.. I did not look into the screen comment btw…. 1) When connected to the SDR via Ethernet cable, at the terminal type – nohup python namOfFile.py & 2) This will

Re: [USRP-users] USRP B210

Making a hardware DDS to generate a chirp in the FPGA is easy, extremely so if you reuse the Ettus code that interfaces the B210 to AD3961 with correct timing. What is very hard in what you propose, is controlling the AD9361 from within the FPGA without an external host. There is a *lot* of confi

[USRP-users] examples using N310 with ext LO

Hi, Are there any examples for using the N310 with external LO? I have gotten some strange results (strange spectral mirror-ing) when using as just a 4 channel receiver. I am using the "args" argument to set rx_lo_source, but my code is setting the individual channel frequencies as I do for other
