Hi,
I wonder if it is possible to tune the RF frequency in blocks written in c++.
In python, statements as the follow are used to tune the frequency of RF board.
r = u.tune(0, subdev, freq)
I want to adjust the receiver's RF according that of the transmitter automatically with some frequency

I've built an application that intends to output both signals video and audio, but I haven't been able to test it because it requires a lot of computer power.i just added these lines:>>self.u = usrp.source_c(decim_rate=
options.decim,fpga_filename=self.fpga_filename) self.u_audio = copy.copy(sel

All - Do I understand correctly that gr.pll_carriertracking_cc() is
supposed to downconvert to DC? I don't see it doing that, and can't
see in the work functions where that magic would be accomplished.
Just want to make sure I'm building the most efficient graph possible.
I tried both in an exist
You are correct. pll_carriertracking_cc returns the recovered carrier.
Sending to baseband is then done by a complex multiply block, don't
forget the conjugation.

Thanks, Eric. Would you please tell me the exact C++ functions which do the tuning?
Is there any C++ class relating the usrp class in python?

You can shift the frequency by multiplying by a complex exponential.

Hello everybody,I am still a beginner in the project so bare with me if my questions have obvious answers.I
was looking at the verilog code for usrp_std.v module. that module
containes the tx_chain.v module which uses a module called phase_acc. I
am not sure what this later module does? It takes as
