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.Signal Detector detects signal frequency signal strength and data speed of network and WI-FI .
