2.0.3 Scale/Div
Sets the units per vertical graticule division on the display. This function is only available
when Scale Type (Log) is selected and the vertical scale is power, or Demod View is on and
the vertical scale is hertz. When Scale Type (Lin) is selected, Scale/Div is greyed out.

2.0.4 Scale Type
Allows you to choose a linear or logarithmic vertical scale for the display and for remote
data readout.
The scale type for display and remote data readout may be different from the scale used for
averaging processes. For information on the scale used for averaging process, “Avg/VBW
Type” on page 89.
When
Scale Type (Log) is selected, the vertical graticule divisions are scaled in logarithmic
units. The top line of the graticule is the Reference Level and use the scaling per division,
Scale/Div to assign values to the other locations on the graticule.
When
Scale Type (Lin) is selected, the vertical graticule divisions are linearly scaled with
the reference level value at the top of the display and zero volts at the bottom. Each
vertical division of the graticule represents one-tenth of the Reference Level.
The Y Axis Units used for each type of display are set by pressing
YAxisUnits.The
analyzer remembers the settings for both Log and Lin.
