WARNING: Moving data to internal buffer is the time consuming operation.
The reaction to bar movements can take several seconds.
The waveform stored in the internal buffer is displayed on the screen positioned right

(time) and time between the screen cursors (red and blue cross).
VARNING: Any place of the data can be marked by the time synchronization
mark. The real time of the marked place can be set to any value. The real time of
