Adjusting the Horizontal Scale and Offset

Adjusting the horizontal scale increases or decreases the number of seconds per
division (s/div). Adjusting the horizontal offset moves the waveform towards the
left or right of the display. The horizontal scale and offset can be adjusted from
the Horizontal section on the front panel or the graphical interface.
Negative horizontal offset will reduce the sampling rate and cause trace

distortion. It is recommended to set the offset relatively close to the horizontal
scale for optimum performance.
