content: Fromhttps://blogs.scientificamerican.com/observations/the-hippies-were-right-its-all-about-vibrations-man/,Code:These names refer to the speed of electrical oscillations in the various brain regions, as measured by electrodes placed on the outside of the skull. Gamma waves are typically defined as about 30 to 90 cycles per second (hertz), theta as a 4- to 7-hz rhythm, and beta as 12.5 to 30 hz.I already has keysight spectrum analyzer range 10hz -3Ghz,how to measure human frequency around 4-90hz?

content: I'd investigate if there are any cheapy USB audio adapters or PC cards with response that goes down to DC.Your spectrum analyzer is not really going to help, even if you upconvert everything.You're probably going to need a preamp.You're probably going to want to do a bunch of analysis.To start out you'll want a desktop environment, maybe later an accessory for an Android or a standalone µC.

content: Well, OP, just to give you the benefit of the doubt that you actually have a specific technical question.Please confine yourself to one thread. Hopefully in a tasteful font and not too many capital letters.

content: I'm not sure. How would dating sites benefit from making posts like this?My first though was that it's spam advertising some pseudomedical "vibrations" stuff, but now I see that the link is not really commercial and OP made several posts about something along the lines of recording brain waves with a spectrum analyzer and antenna, so I dunno. Maybe just crazyThe pic is simply stolen from an Intstagram user.

content: i don't mean the post content but the style of setting up a profile, use a random picture off the internet and use random numbers in any registration. They did at least use a real sounding username.On dating sites I see so many profiles that are a name followed by numbers, if there are more than 4 it is definitly a scam but usually more than 2 it is too. they just want to generate something so unique with no effert that they can get the email account registered and the profile. Then they use some picture scrapped off the internet from underwear adverts to other social media sites and then they copy the profile content of another account. Makes them so easy to spot.
