I have an Atom D-510 running Fedora 12, and the latest UHD+GnuRadio (as of this morning).
I've noticed that if I turn on "Peak Hold" in the FFT display, the entire input side of the GUI becomes unresponsive to input, even for low input bandwidths, where the CPU usage is quite low. Anyone else seen this? I can easily reproduce this with a simple: UHD:Single-USRP source ------> FFT Sink (Update rate 5, Averaging on, Peak Hold on) It doesn't seem to depend on input bandwidth--even as low as 250KHz input bandwidth, setting Peak Hold causes the GUI to become unresponsive (although the FFT display continues to update). -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
