Hi I am using Gnuradio v3.2 and usrp1. I was using modified examples\digital\transmit_path, receive_path to send and receive packets on the RFX2400. This was working alright.
I wanted more transmit power (+ adjustable gain) so I exchanged the RFX2400 boards for XCVR2450 boards. However when I run my packet transmitter program (which worked fine with RFX2400) the XCVR2450 boards did not transmit! The program was not reporting any errors, but looking at on usrp_fft or on a spectrum analyser, no signal was being output. Likewise with my receiver: running usrp_fft with the XCVR2450 it could not pick up signals. Do I need to add in extra things to my code to get it to work with XCVR2450 boards? I set the gain on the subdevs to maximum. Do XCVR2450 boards work with usrp1 and gnuradio v3.2? Another question: When I transmit a packet it should occupy only a limited bandwidth from the RRC filter. However in actual fact, running it causes quite a jump in the noise floor. I also noticed with siggen that there were considerable sidebands/harmonics being produced. Is there a way to reduce or eliminate effect of packet raised noise floor / harmonics? I am working at ~2.4/2.5GHz (since my antennae work at this frequency, although I am currently swapping between antennae and SMA cables) -- Posted via http://www.ruby-forum.com/. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
