Radio frequency detector.

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.
