Hi I need to figure out exactly what is happening to a captured signal from the moment it enters the TVRX daughtercard to the moment it enters the PC. At this moment I am conducting some experiments on the TVRX card. I need to measure the signal that leaves the card and enters the ADC. My understanding is that pins 17 and 18 of this module are a differential output. We don't have a differential probe, so I'm using CH1-Ch2 and displaying this. My understanding is that if I input a 100MHZ sine wave to the TVRX card, a 5.75MHZ sine should be leaving it (we have a 3x7901 tuner module). When I measure this signal, I just get a random noise signal or something. Could someone please help me?
Thanks. Sebastiaan Heunis _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
