Hello all,
I want to know how I could possibly find out the complete
details about the BPSK-Signal generated by the
benchmark_tx.py GNU Radio script.
Should I look at the code and at which file respectively?
Thanks in advance.

I assume you are talking about the benchmark_tx.py under narrowband/
directory. With my (limited) experience with it, I can tell that it
depends on code in transmit_path.py under the same directory. The
packets related function can be found at gr-digital/python/{pkt.py and
packet_utils.py}. As with the modulation, it utilizes the code in
gr-digital/python/generic_mod_demod.py. So have a look at these files
you will get some more information about how the blocks are connected.
When you want to know the implementation/algorithm of blocks, you will
need to look into the C++ code (under lib/ and include/ directory).
Besides, the benchmark_tx.py script has a option ‘–log’, which can be
used to dump the output data of some blocks into files. You can then use
Octave/Matlab to read these data files and play with them(by plotting,
etc). To read the data files into Octave vectors you can use functions
described here.[1]
