Setting Horizontal
Size and Position
3 106
You can change the horizontal magnification, or size, of a trace. You can
also move the trace left or right to see different portions of the trace. This is
called adjusting the horizontal position. To do either of these, touch the
horizontal ( ) icon. This assigns the knobs to adjust the horizontal size
(top knob) and position (bottom knob) of the selected trace.
The axis label for the left edge of the graticule is slightly different than the
horizontal position of a trace. This is because traces extend slightly beyond
the edges of the graticule. The illustration on the previous page shows the
main position (the knob label) is 59.5 ns, and the left edge of the graticule
is 58.5 ns.
If you want to change the size or position of a different trace, touch the
desired trace to select it. Then you can use the knobs to adjust horizontal
size and position.
Touch a knob label to display the Keypad pop up menu. This lets
you set horizontal size and position numerically, or quickly set them
to maximum or minimum limits. It also lets you set the knob resolu
tion.
Interactions With Other Traces
The knob labels tell you whether the selected trace is from the main time
base or a window time base.
All traces from the main time base share the same size and position. If you
change the size or position of one main trace, you will change the size or
position of all of main traces.
All traces from window time bases have the same horizontal size. If you
change the horizontal size of one window trace, you will change the horizon
tal size of all window traces. Each window trace can have a unique horizon
tal position.
