Abstract ：A design method of novel spectrum analyzer is proposed in this paper．Firstly ，the method can make analog-to-digital converter as close as possible to antenna．Secondly ，the universal software radio peripheral realized simple signal processing．Thirdly ，it realized signal spectrum analysis...
you have a larger range than you'll ever need concerning the machine, but some sinks and sources have specific ranges you need to stick to. For example, audio sinks require samples within +-1 and will clip anything outside this interval. The USRP sink on the other hand needs samples in ...

I played back the recording with the USRP feeding a spectrum analyzer through a 20dB pad. I can adjust the level of the digital stream, and I can also inject a single CW tone at the center of the band. Here is a screenshot of three conditions captured using the “max hold” trace fu...
Most blocks you'll be using at the beginning are either from thegr,audioorusrpmodules. So if you find a class calledgr_sig_source_fin the auto-generated docs, you can create this class in Python by callinggr.sig_source_f(). At this point it is worth having a closer look behind the...
