Hi Marcus, I am looking at the following link https://files.ettus.com/schematics/x300/x3xx.pdf and as you said same clock is being used by both the boards. NI has asked for some time to find it out. Regards, Koyel From: Koyel Das (Vehere) Sent: Monday, S

[USRP-users] custom E310 bitfile weird new error

2018-09-17 Thread Jason Matusiak via USRP-users
I had a system that worked pretty well for creating a new bitfile for my E310. I ran through all the steps again so I could make sure that my notes were OK, but now I get an error when I run a probe on my E310 using that bitfile. I copied over the bitfile and replaced /home/root/localinstall/

Hi Marcus, My colleague suggested not to use TX/RX port and I did that. I just tested two sets of data of stationary wifi with both antennas this time connected to RX2 port as he suggested and then the phase difference deviation goes maximum to 0.3 rad. I will carry out experiments with more da

[USRP-users] RFNoC TX Examples

Hey everybody, Is there anywhere I could find C++ examples of a TX stream using RFNoC blocks? The latest rnoc-devel commit only has two RX examples, and I cannot seem to replicate the behavior from that. Thanks, Leo ___ USRP-users mailing list USRP-use

Martin, I can only find methods to write the user registers, poke32() and set_user_register() using the less invasive access method. Is there a peek32() or get_user_register() method to read custom registers in the user_regs address space? Thanks, Mark _

Hi Marcus, yesterday I got the deviations of 0.3 rad by fluke. Even after receiving using two RX2 ports the phase difference is deviating to large values like 2 rad. I tried disabling I/Q corrections by passing 0 to the property field but that too didn't work. I think I really now need to use
