[Discuss-gnuradio] question about data using read_comple_binary.m

[James Park]

Hi,

 

I add self.file_sink to benchmark_ofdm_tx.py

 

self.file_sink = gr.file_sink(gr.sizeof_gr_complex, "filename.dat")

welf.connect(sef.txpath, self.file_sink)

 

and looked at the data with read_complex_binary.m

However I am confused with units of x and y axis.

for exameple, if I get 2.5e6 for total x value, can I divided it by 64M for translate into exact time(second)?

also, using rfx2400 and how can I get dB of y axis? I am confused between amplitude options and real amplitude.

Thank you.

 

James,
