I am still quite new to the USRP and GNU-radio, but I managed to write
first piece of code for the USRP to behave like a network-analyzer. I
1)I would like to just dump 2X-1000 complex samples into 2 files and
quit (without keyboard or mouse interaction). But after calling tb_run()
never see the prompt again unless I manually kill the job. I do get the
expected content in the files.
2)I would like to use just a single DAC-output (Say DAC 1 of Side A).
Reading the spec of the AD9860 I was expecting to get this by setting
self.tx.set_mux(gru.hexint(0x00000080)). But it seems that DAC 0 and DAC
always output I&Q-signals. It does not seem to have any effect whether I
usrp.sink_s and gr.sig_source_s or usrp.sink_c and gr.sig_source_c.
BTW: my USRP is populated with 2 LF-TX and 2 LF-RX boards.
Any hints would be very welcome.
I attached my piece of code.
