Hi GRC companions
Has anyone used GRC to acquire a large range RF spectral survey?
Basically, step from range to range, and save the output in a (text)
file. I would like to be able to average each frequency/range for some
(variable) period of time, or do peak hold, much like some of the nice
FFT sinks do. I have been doing this in Python with a modification of
osmocom_spectrum_sense, but I would rather use GRC since it is more
intuitive. I just need a starting point, and particularly how to save to
file, and time average. This seems like it would be pretty
straightforward, but I haven't seen it done anywhere (with GRC).
A little background. I am working on a research project on ambient RF
energy harvesting (using printed metamaterial antennas). I recently got
a HackRF One to help understand the ambient RF energy present and
correlate it with energy harvesting performance.
Thanks in advance!
