Scale/Div
For measurements that support a logarithmic Y-Axis, Scale/Div sets the height of
one division of the graticule in the current Y-Axis unit.
Scale/Div also determines the displayed amplitude range in the log plot graph.
Since there are usually 10 vertical graticule division on the display, the total
amplitude range of the graph is typically 10x this amount. For example, if Scale/Div
is 10 dB, then the total range of the graph is 100 dB.
In measurements that support both Log and Lin scales, this function is only available
when Display Scale (Log) is selected, and the vertical scale is power. When Display
Scale (Lin) is selected, Scale/Div is grayed out.
For the Harmonics measurement: The displayed Scale/Div is identical for all
harmonics displayed.

Y Axis Unit
Displays a dropdown menu that enables you to change the vertical (Y) axis
amplitude unit. This setting affects how the data is read over the remote interface.
When using the remote interface, only numerical values are returned, so you must
know what the Y Axis Unit is to interpret the results. This is described in more detail
in "Amplitude Data Query and Y Axis Unit" on page 1764 below.
For measurements that support both Log and Lin scales, the instrument retains the
entered Y Axis Unit separately for both Log and Lin amplitude Display Scales. For
example, if Display Scale has been set to Log, and you set Y Axis Unit to dBm,
pressing Display Scale (Log) sets the Y Axis Unit to dBm. If Display Scale has been
set to Lin and you set Y Axis Unit to V, pressing Display Scale (Lin) sets the Y Axis
Unit to V. Pressing Display Scale (Log) again sets the Y Axis Unit back to dBm.
