Re: [USRP-users] [Discuss-gnuradio] Boost 1.66.0 Compatibility: GNU Radio & Volk & UHD

2018-01-05 Thread Michael Dickens via USRP-users
I and other MacPorts developers have been testing out boost 1.66.0 for a while now & it seems very stable. There are a ton of ports that rely on Boost, and it takes time to go through them to verify that they at least build & hopefully function too. I expect we'll be updating from 1.65.1 by mid-Jan

Hi David - It looks like you have 2 versions of UHD around, both of which are in standard install locations (/usr and /usr/local). This can cause confusion / issues when running executables for either install. I'd advise you to pick one UHD install and remove the other; you might have to even remov

The AD9361 has internal compensation for DC offset and I/Q imbalance. Make sure that you’re running with a recent system image for E312. Sent from my iPhone > On Jan 5, 2018, at 5:18 PM, Xingjian Chen via USRP-users > wrote: > > Hi, > > Is there any way for E312 to self-calibrate? I found

[USRP-users] IQ imbalance calibration for E312

2018-01-05 Thread Xingjian Chen via USRP-users
Hi, Is there any way for E312 to self-calibrate? I found there is IQ imbalance in amplitude and dc offset showing in the recorded signal's real and imaginary part. But it seems that its daughter board is not supported for self-calibration. Any idea to solve this? Thank you very much. __

Thanks for the explanations. I originally though the DDC block was only for the X310, but that makes more sense now, I figure I could retune while in a flowgraph by changing the ddc parameters. 10 Microseconds in fast enough for my current application (spectrum scanning for packets in different f

Hi all, My B210 on Ubuntu 16.04 *used* to work fine. I recently downloaded and compiled ( & install) new host dev source /lib binaries ( examples etc) , NOW I cant see my B210. ( Its still phys there in dmesg) Ultimately I want to be able to compile and run my own C++ code through the UHD API. T

Ha! That image looks very much like a copy of an image I did a couple of years ago to explain offset tuning :D Anyway, you're still not answering my core question. I can't help you if you don't do that, and since you're only repeating what you've already said, I'm afraid that means that we've come

[USRP-users] Reading data from RF Channels and Spectrum Sensing module

Dear All, I'm planning to put together a system composed of a MIMO physical layer and a spectrum sensing module. For this task I will be using one x310. The spectrum sensing module will be implemented on FPGA and will apply an algorithm to the received IQ samples and output a vector with 128 valu
