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.Radio frequency detection. Hidden camera finders that use RF detection pick up on the radio waves used by wireless cameras to transmit information. These can detect signals anywhere from 1MHz to 10GHz or higher, depending on the finder. More professional finders are able to detect a greater and higher range.
