do these even exist? I want something that'll give me a graph of all EM radiation happening at a certain point and by "all" I mean all. from 5 Hz all the way up to gamma rays
Anything analogue should be pretty broad spectrum. a lot of the digital meters are intentianally compromised to suppress certain frequency ranges
>>16795726Just put the detector of each band side by side and connect their amplified output to a microcontroller after a sufficient amplification. In the microcontroller you do the signal processing and get the field strength.You need to use many multi-turn ferrite rod loop antennas, regular loop antennas, ultrawideband antennas (fractal, spiral etc.) photodetectors and geiger counters.
