Hi,
I want to transmit fixed numbers of sample from the
sin_sig_source.And I find the issue_stream_command in
multi_usrp.hpp.Does the command contral the flow graph so that I just
connect the flow graph and add the command in python? I appreciate any
tips.
Thanks in advance.

Issue stream command is for RX, and this is exposed in python, so you
can call it.
Now for tx, if you wanted to transmit a fixed number of samples, its
best that the producer of data frame the end of its bursts with a EOB
tag. But I suppose something quick and dirty would be
sig_source → head → usrp_sink
A few examples here w/ the tags:
