[Discuss-gnuradio] Problem displaying magnitude of a complex signal in a scope sink

[Louis Girard]

Hi,
   I started developing with GNU Radio a couple of weeks ago and have been
following the list for a while. I must thank Eric, Matt and everyone else for
all the time they are devoting to this project. Now with my problem...

I am trying to do something which should be pretty simple. I have started from
one of the examples provided with GNU Radio. I use the USRP as a source for
complex data. Then I use gr.complex_to_mag() to get the magnitude of the
signal. Finally I output it to the scope using scope_sink_f. What I get is a
single freezed frame on the scope and nothing after. It is probably a stupid
mistake on my side. The code is in attachment.

I am using GNU Radio release 2.8 as I don't have access to CVS on the system.
All the examples work well on my system. I tried the code on a basic and a
dbsrx daugtherboard.

Is there any additional documentation available for gr-wxgui?

Thanks for your help,

Louis
