To scale the Y-axis with Reference and Y Per Div softkeys
1 Activate the trace you want to scale.
2 Press [
Scale
].
3 If you want to change the top of the display, press [
TOP REFERENCE
]. If you want to
change the center of the display, press [
CENTER REFERENCE
]. If you want to change
the bottom of the display, press [
BOTTOM REFERENCE
].
4 Turn the knob, press an arrow key, or enter a number to change the reference value.
5 Press [
Y PER DIV (DECADES)
], then turn the knob, press an arrow keys, or enter a
number to compress or expand the trace along its Y-axis.
When you adjust the value of [
Y PER DIV (DECADES)
], the currently-active reference
(top, center, or bottom) is held constant and the rest of the Y-axis is compressed or
expanded around this reference. [
Y PER DIV (DECADES)
] specifies the number of
decades between the top and bottom of the Y-axis when the log magnitude coordinate
system is selected; it specifies the distance between graticule lines when any other
coordinate system is selected. (The coordinate system is selected under the
[
Trace Coord
] hardkey.)
Hint: The reference softkey with a box around it is the currently-active reference.
With [TOP REFERENCE]
selected, this value remains
constant as [Y PER DIV] changes.
