In the oscilloscope window feedback signal, deflection signal (ADC#0) or friction signal (ADC#2) can be presented. User can switch between this signals using the buttons on the right from the Oscilloscope window. Signal, showed by oscilloscope automatically scaled in following way - 0 should be in the center of the window, all signal fits the window, positive values represented in upper window part. On the right of the window is a 15-segment logarithmic scale indicator, every segment of which corresponds to 1 signal bit.
