The scrollbar on the left side controls the sampling frequency. The actual
sampling frequency is shown above. Usable values are 50S/s to 5MS/s settable in 1-2-

WARNING: The fastest sampling frequency is usable only if the oscilloscope is
connected to computer via USB 2.0 interface. It is strongly recommended to close
any other application and choose the "Rew" display mode or switch the
oscilloscope display off (see chapter 4.4.). If the oscilloscope is connected to
computer via USB 1.1 interface the maximum usable sampling frequency is
250kS/s.
The scrollbar on the right side controls the display timebase. The following
information are displayed above this scrollbar:
- time of one grid division
- 1/time of one grid division
- number of samples aggregated to one screen point
TIP: For more information about display mode please see chapter 4.6.
If the change of one scrollbar results in lack of samples to create the dot, the
position of the second scrollbar will be adjusted to get one sample for each displayed
dot.
WARNING: If the scrollbar position is adjusted due to above mentioned reasons
automatically, it won't be readjusted back, when the reasons are gone.
