When I send this to file_sink, I see correctly 16 samples from peak to

Hello all,
sink = usrp.sink_c(0, 64).
I am confused about the function sink.set_tx_freq(0, 5e6).
What does this do? I already know the receiver must be set to listen at
5e6 Hz. But what does the function do to my signal?

Can you please post it?
Between the time of originally posting and now, I changed the length of
the vector and now am able to see a decent received signal.

Hello all,
I am new to gnuradio and communication theory.
I am trying to multiply two signals by their corresponding elements. I am
trying to mimic amplitude modulation.
I already have source1 which is a sine wave generated by sig_source_c.
There is source2, which is a vector source generate
