[Discuss-gnuradio] compare data from usrp_siggen.py and usrp_oscope.py

[James Park]

Hi,

 

I compared the data from usrp_siggen.py and usrp_oscope.py using matlab,

but wave from usrp_oscope.py data has twice longer wavelength.

Could you tell me why this happaned? do I have to change the parameters?

Also, I added the

 

self.connect(self.txpath, gr.file_sink (gr.sizeof_gr_complex, "data.dat"))

 

in the benchmark_ofdm_tx.py to get data.

However, there are huge amplitude difference between the wave from usrp_oscope.py data and the wave from benchmark_ofdm_tx.py data.

I used the function http://gnuradio.org/trac/wiki/Octave

Could you give me some idea?

Thank you.
