1) uO means usrp overrun, i.e. the usrp had more data to send, but the host computer was not fast enough to accept it and calculate it, so it was dropped. setting the decimation rate to its maximum value does decrease the processing load on your cpu, but on old systems or very "heavy" flowgraphs your cpu might still be overloaded. try closing any other programs running (e.g. don't watch youtube videos at the same time)
2) no, the decimation and interpolation rates don't need to be equal, but their combined values need to not saturate the usb 2.0 bus Dimitris Symeonidis "If you think you're too small to make a difference, try sleeping with a mosquito!" - Amnesty International On Mon, Apr 6, 2009 at 20:14, <[email protected]> wrote: > Hi, > > I have a few basic USRP questions.
