How to generate a CW sine signal?

farhan296 · 20 December 2019 21:54

Hello,

Can anyone help me with this. I want to generate a single frequency continuous sine way at around 2.47 GHz. How can this be achieved using C++ on LimeSDR or a system with LMS7002m chip? Also which registers do I have to configure in order to get a single tone like gain,Dc correction, I/Q imbalance correction etc? Can anyone share a configuration file. AlsoI do not want any modulation. I will appreciate your help in this regard.

Thanks.

Hi!

Why don’t you use gnuradio and gr-limesdr OOT block? It’s an easy to use application which allows to do signal proccesing in python or c++ language.
