Hi All, I have a pair of USRP N200s with XCVR2450 daughterboards running the latest GNU Radio version with UHD. This is an odd problem, but I'm wondering if anyone has seen this before.
When I run the benchmark_rx.py/benchmark_tx.py specified at 2.4GHz, the transmitter is transmitting images of lower magnitude at +/- 0.5MHz, and the receiver isn't able to decode any radio packets. Some frames are received, but they are all "ok=FALSE" with the lengths lower than the length of the actual packet sent. These images persist when I set the XCVR2450's to tx/rx within its specified frequency range. note: the benchmark scripts are from ~/gnuradio/gr-digital/examples/narrowband/ However, when I run the benchmark scripts at "--freq 0" on both sides, the transmitter says it is automatically set to "4800MHz" (although this is outside of the XCVR2450's range), and the receiver says it is automatically set to "2400MHz." Somehow, the transmitter is transmitting at 2.4GHz and the receiver is tuned to 2.4GHz. The signal is clean, and there are no images in sight. I used both uhd_fft.py and a spectrum analyzer to check. Does anyone have any idea what's going on? -Jason -- View this message in context: http://old.nabble.com/benchmark_xx.py-Transmits-Images-at-%2B---0.5MHz-When-Center-Freq-Is-2.4GHz--USRP-N200-and-XCVR2450--tp33763401p33763401.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
