[Discuss-gnuradio] Re: USRP / DBSRX calibration
Hi. I'm trying to estimate the noise temperature in the DBSRX and USRP as a part of a student project where we compare the USRP as an alternative for the receiver in a radio telescope. I tried to convert the -165dBm/Hz to Kelven but I'm not getting a sane value. I may be way out here but would be very pleased to find out what the noise temperature might be, in Kelvin.

[Discuss-gnuradio] USRP Self check
Hi! Does anyone have a system check program for the usrp? /Staffan -- Posted via http://www.ruby-forum.com/. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] Problems after replacing the F501 fuse
Hi. After blowing up and replacing the F501 fuse the USRP is found by the computer but it doesn't give me any signal. The usrp_fft.py-window is emty accompanied with the error message "Faild to set initial frequency" and the benchmark stops working at 2MB/s. We believe the ADC is damaged. Is there anyone out there with similar problems or a solution? -- Posted via http://www.ruby-forum.com/. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
