signal amplitude.
The information area in the upper left corner of the “Spectrogram” display shows the real-time of
the latest spectral data (relative to the start measurement), the total number of generated
waveform frames, and the waveform display range.
In the "paused" state, the user can observe the historical trace by moving display trace (D1, D2),
or the historical range of the waveform data displayed in the waveform area by view start and view
end. In the run state, the view interval offset is 0 by default, that is, the latest historical data is
displayed, while D1 and D2 are the latest trace by default.
Reading makers on traces D1 and D2, observe the position (time of occurrence) of the
corresponding traces in the historical data, as well as the frequency and amplitude of signals.
Compared with the latest trace, it can trace up to 50000 frames in the future. When the total
number of generated waveforms is more than 50000 frames, the historical data of more than
50000 frames will be discarded.
