[Discuss-gnuradio] USRP USB not responding

2005-08-01 Thread EDWARD HALL
My USRP board has developed a USB communications issue.  The host PC no longer responds to the board when the USB connection is made.  “USRP” does not show up in USBview, and the FPGA does not load.  The green flashing LED on the board continues to flash at the faster rate.  I can see two

[Discuss-gnuradio] getting mouse position

2005-08-01 Thread cswiger
WxPython gurus - I'm looking to get accurate readings from fftplot. Any clue appreciated: wxMouseEvent has a function GetPosition(). When I bind an event like wx.EVT_LEFT_DOWN to something like self.click() which just prints GetPosition() nothing happens. self.mouse = wx.MouseEvent() self.Bi

[Discuss-gnuradio] Still confused about the IF frequency

2005-08-01 Thread Sachi
Hi, Eric and Matt I still can't understand the question I asked in July 26th's email. Hope you could take a look at the email titled "confusion about set_rx_freq()". My understanding is, if we get a "reversed version" of the spectrum, we eventually get the "conjugate version" of the signal in ti

[Discuss-gnuradio] 8 MHz Spur on USRP?

2005-08-01 Thread Clark Pope-TWC
I have a USRP with RX and TVRX daughterboards. With spectral displays on both I get a large spur that's 2.25 Mhz from the 5.75 MHz that the DDC is programmed to. So I conclude that its actually 8 Mhz probably a subharmonic of the 64 MHz ADC clock. Do other USRP users see the same spur? Or do I just

Hi All,   We are implementing our algorithms on USRP board, and our flow goes like this :   Transmitter part:   Audio input from PC --à Modulation (not a standard modulation as in USRP examples, we are implementing our own modulation technique specific to our application , and we hav
