Hi sir,
I have ran the uhd_msg_tune.grc,but its quiet hard to understand the python
code for me. 

I just set the sample rate to 40M, and centre frequency to 2.4G, it comes
out power against the frequency of the signal and the graph seems more
static than dynamic. 

I wonder how it achieved without fft, and how to export the raw complex data
instead of power? 

cuz I want to install the gnuradio into a embedded system instead of PC, I'm
working on the data collection, after get the raw data, I will pass it to
the FPGA for the fft, and the output will be further processed for signal

Thanks a lot
