[Discuss-gnuradio] Allign LOs for SBX boards

[Dominique Guelord Ingala]

Hi, I need to allign the LOs for SBX boards. I read the application notes on UHD-Synchronization.

http://files.ettus.com/uhd_docs/manual/html/sync.html#align-los-in-the-front-end-sbx-wbx-n-series

I've been working on this for a while, but I'm still confused a bit. Please what is the directory for the UHD source and sink blocks where the timed command must be applied. Which part of the code must be changed in these files. Also how will I know that the LOs are now alligned. 

I'm using ubuntu 11.10. I found 2 files (gr_uhd_usrp_source.cc and gr_uhd_usrp_sink.cc) under the directory : gnuradio/gr-uhd/lib.  I'm not sure if these are the right files where the timed command must be applied. I tried some changes in this files, but there is no reaction from the USRP. 

Your answer will be appreciated.

Regards.

Dominique.
