I want to build a network analyzer using the usrp with LF-RX/TX.
I am new to gnu-radio and usrp and so far only managed to send an
receive based on the examples usrp_rx_cfile.py and usrp_siggen.py.
I think I pretty much understand the code.
It seems I cannot have two derivatives of gr.top_block (one for RX one
for TX) within one module?
Using class transmit_path(gr.hier_block2) and
class receive_path(gr.hier_block2) as in usrp_nbfm_ptt.py
looks like and overkill for my purposes, as I don’t need any
demodulation nor base-band filtering for my network-analyzer.
Any suggestions for a straightforward approach would be more than
