Hi, I am a beginner in USRP for GNU Radio. I just buy two sets of USRP with RFX900 for our project. There is no any documents together with the package. That is fine for play USRP monther board. I have test the USRP and it is fine. But when I want to test a transmitter and receiver between two sets of USRP+RFX900, there is no any documents address this. I have to find which file may be used to test RFX900, and furthermore go through all the codes in that file to decide how to build up a link between two RFX900. Since there are almost no comments, it is very difficult for many beginners like me to understand. Does anyone have suggestions for: 1. which files should I use to test link between two RFX900?
Just change the carrier frequency, you may use a lot of files for test. For example, usrp_fft.py, usrp_nbfm_ptt.py, usrp_nbfm_rcv.py etc. http://gnuradio.org/trac/browser/gnuradio/trunk/gnuradio-examples/python/digital is a good example for full duplex transmission. 2. which file may I use to set the power gain for trasmitter?
since my experience before is LNA in receiver has maximum input power limit.
Only the software gain. I mean the data you give to DA. 3. which file may I use to set different waveforms? 4. Is there such documents addressing these for beginner?
Thank you very much!
http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html "how to write a block" is a document for beginner. And http://www.nd.edu/~jnl/sdr/docs/tutorials/ is a good tutorial, but maybe not updated for a long time. Hope they are helpful for you. BR HUANG Lin Best Regards,
