8. Spectrogram

ming zhong -

The spectrogram is a visual representation that shows how the spectral density of a signal varies with time. The figure shows frequency on the x-axis and time on the y-axis.

Read more about spectrogram on Wikipedia.

Similar with Spectrum mode, you can also change the scale of the x-axis to logarithmic, linear, or to display note names just by highlight the LOG[2], LIN[3] or ST[3] buttons. The display can be locked by tapping the “Spectrogram (FFT)”[4].

MF[5] button is highlighted by default, which means that the display shows frequency from 100Hz-1KHz (aka medium frequency area). You can switch FFT Tuning Unit to show frequencies between 10Hz-10KHz by tapping the MF[5] button again.
