Let’s start off by talking about one of the more popular EMF detector apps on the apple app store, EMF Scanner. I downloaded this app and used it for a while, and was surprised that it gave readings when it should. Step 2: Mid Point Detection. I decided that I would get more accurate results detecting the frequency of a wave by keeping track of the times the wave crosses 2.5V instead of counting peaks. In the last step I was essentially finding the places on the wave where the slope = 0 and counting the time between these events.This means that the period of the wave is 4ms, or 0.004s, giving a frequency of (1/0.004) = 250Hz. If you change the timebase to 500µs (half of what it started at), you should see the waveform now takes 8 squares to complete one full oscillation. The period (and hence the frequency) remain constant because 8 times 500µs still equals 0.004s.RF and Microwave Detectors:- About, Types, Application, Design: An RF and Microwave detector is a passive two-terminal device used in an RF circuit to detect the RF power in the transmission medium.
