6. Press the Scale button in the sub-menu to select Vertical.
7. Select Origin from the sub-menu. Use the numeric keys or the general
purpose knob to input the numeric value of the origin.
This value is used as a reference when scaling vertically. It may be set to any
value between –1.0000 and +1.0005 for the full scale of the vertical axis.
8. Select Factor from the sub-menu.
9. Use the numeric keys or general purpose knob to input the scaling factor.
Factor can be set within the range 100 in steps of 0.01. A negative factor
causes the waveform between the vertical bar cursors to produce a mirror
image about the origin value.
Scaling with a factor under 1.00 and greater than –1.00 ( 0.99) reduces the
waveform vertically between the vertical bar cursors. Scaling with a factor
greater than 1.00 or less than –1.00 expands the waveform vertically between
the vertical bar cursors. Waveform data pushed beyond the full scale of the
vertical axis by scaling is clipped.
10. Select Execute from the sub-menu. The waveform is scaled with the
specified conditions.
Figure 3 -31 shows an example of Factor being used to enlarge the section
of the waveform between the vertical bar cursors. In this example, the
waveform has been enlarged 1.5 times vertically around the reference line.
