So, out of curiosity, how do you think the signal was taken in from the antenna in that paper?

I would like to do EM scans around my house just out of curiosity, and the graph is nice.

Is this an application for a cheap usb software defined radio, or is this the output of a several hundred dollar oscilloscope?

My EMI knowledge is almost zero, but I think you can see a couple of examples and projects with interesting information (and cheaper options) about it here in the RTL SDR blog with the 'emi' tag: https://www.rtl-sdr.com/tag/emi/

In fact I'm going to read it later
