Thanks Josh;
One of the boxes was disabled, as you said.
Thanks Marcus;
I changed the sample rate as you suggested.
So. I now have three problems remaining:
1) I need a way to start and stop the scan. I added a
variable_chooser (Button) and a "valve"; but I don't know how to control the
valve using the button.
I checked the wiki and apparently, because the Open
parameter is underlined this means it can be controlled by the graph when it
is running.
I couldn't find any examples of how to use the valve.
2) I think I need a throttle somewhere, because the USRP Source
and the FFT Sink appear to be out of sink. Also the FFT Sink controls do not
respond .
3) I am using a Sawtooth as the signal source. I appears that I
can control the Amplitude and Frequency much like the Open parameter in
Valve. This would
be REAL handy for controlling the sweep rate (frequency) and
for resetting the sweep (amplitude). But once again I don't know how L
Thanks Again Guys for all the help J
