All, I wanted to resurrect a problem that I had couple months ago that
I put aside and would now like to fix. The issue is that I get a python
error when executing a flow graph on an E310 that was generated from GRC.
The error is posted below. For background I'm using UHD 3.15 with GNU

The maximum power at any receive port should not exceed -15dBm.
If you’re doing full duplex into a shared antenna then yes you need to use a
duplexor.
This isn’t strictly a USRP issue—it’s a generic RF engineering practice that is
older than most of us here.

Hi all ,
If I use my USRP b210 without duplexer to transmit and receive the signals
from other USRP , will it not damage my USRP ?
Thanks

I can't comment on issue #1, but I do have experience with issue #2. To
get a clean output spectrum, you need to do two things.
First, the IQ values generated by your application can never exceed
+1.0/-1.0 in value. You have to account for the PAPR of your waveform.

Thanks Jim,
That fixed it, would never have found that one!
Looks like Ettus need to fix this bug in rfnoc_image_builder for future
releases.

It's been a while since I did this, but I had issues bringing up the gui as
well. Here is a copy/paste of some notes I wrote for myself:
* Edit the file "$PREFIX/bin/rfnoc_image_builder".
* Find the line "gui=args.GUI" and change it to "GUI=args.GUI" and save it.
* Next, edit "$PREFI
Wade, usrp-users,
I’m now trying to build some code in an OOT directory.
I can build the design with the rfnoc_image_builder Ok, however I can use the
two step workaround to get the Vivado GUI to open. When I try and run “make
E320_1G GUI=1” I just get an error saying that there is no rule to m
Hi all,
Did anyone get an initial sync issue with OAI UE and OAI enb connection . I
am using USRP B210 for eNB and UE. Please help!!
I dont know what power parameters i have to use to calibrate this setup .
How to go further and solve this problem?
Thanks
