30.9 Reference Position Setting
The reference position is used to set the strategy of scaling on the horizontal and
vertical axes, adapting different requirements.
Operate Utility>Reference Pos to open the dialog box, and choose the strategy for the
offset value change in the vertical (or horizontal) direction when the vertical (or
horizontal) scale is changed.
Horizontal Ref
•
Fixed Delay: When the timebase is changed, the horizontal delay value remains
fixed. As the horizontal timebase scale is changed, the waveform expands/
contracts around the center of the display
•
Fixed Position: When the timebase is changed, the horizontal delay remains fixed
to the grid position on the display. As the horizontal timebase scale is changed, the
waveform expands/contracts around the position of the horizontal display.
Vertical Ref
•
Fixed Offset: When the vertical scale is changed, the vertical offset remains fixed.
As the vertical scale is changed, the waveform expands/contracts around the main
X-axis of the display
•
Fixed Position: When the vertical scale is changed, the vertical offset remains fixed
to the grid position on the display. As the vertical scale is changed, the waveform
expands/contracts around the position of the vertical ground position on the
display.
Take Horizontal Ref as an example to demonstrate the scaling effect of different
settings:
