[Discuss-gnuradio] USRP Clipping?

I am using N210 USRP's with WBX daughtercards connected with a loopback kit implementing a 8-PSK waveform. When I start transmitting, I get a clean constellation. After a short time however (~5 sec) it appears that the receiver temporarily loses phase lock. The eight point constellation degrades su

Re: [Discuss-gnuradio] Gnuradio-Companion Documentation.

Docs can take a long time to build, so when doing multiple builds a day during testing you really don't want to have this turned on. Likewise if you are building on slow machine or an older machine without sufficient doxygen. But obviously they are valuable for users doing their primary build

[Discuss-gnuradio] USRP1 gain

Hi ll guys, I am using for my application usrp1 and wbx board. From the documentation I got that maximum amplification value of 20 db, but in my flowgraph I am able to specify without problems more gain for usrp source block. If I put >20 db I really see changes in noise level, which means that so

Re: [Discuss-gnuradio] Gnuradio-Companion Documentation.

I just had the experience of how much the documentation build process can slow down the build in general. So I think a flag that can be set/unset during the pybombs configuration / reconfiguration process is a good idea. And it would make it easier for new users who a: most likely want documentatio

Ok, but as far as I have seen it is fixed and the only adjustable gain should be at PGA in front of the adc. Am i right? On Thu, Sep 19, 2013 at 5:10 PM, Marcus D. Leech wrote: > On 09/19/2013 11:03 AM, Nemanja Savic wrote: > > Hi ll guys, > > I am using for my application usrp1 and wbx board

Can you describe for us what the "loopback kit" comprises? Theres hopefully significant attenuation in the signal path. On Sep 19, 2013, at 7:53 AM, "Marcus D. Leech" wrote: > On 09/19/2013 10:45 AM, Isdren Gineer wrote: >> I am using N210 USRP's with WBX daughtercards connected with a loopback

Re: [Discuss-gnuradio] USRP Clipping?

OK, good, I'd never noticed that on the price list! So 30db is a good value to protect WBX from physical damage in a loopback configuration. It does however leave you with a potentially very high signal level at the RX and so it makes sense that your setup appears to be operating at the edge of
