Hi,I'm new to radio and I have a lot to learn. I have a question about oscilloscopes and the usrp_oscope.py.
I believe the following. Please correct me where I am out to lunch. There is a strong 103.3Mhz FM station in my area. Connect an antenna to a band pass filter that passes 103.3Mhz +- a little bit. Plug the output of the filter to an oscilloscope (a real one) and you will see a 103.3Mhz wave. Note: you do not tune the oscilloscope.
My questions about usrp_oscope.py: How do I see the carrier wave at 103.3Mhz? What are the units of the Y axis? Why does it want to tune? What is usrp_oscope.py showing me? Thanks! Chris
