2.1.3.5 Scale Type
Sets the Scale Type of Y-axis to Lin or Log, the default is Log.
Key Points:

In Log scale type: the Y-axis denotes the logarithmic coordinates, the value
shown at top of the grid is the reference level and the grid size is equal to the
scale value. The unit of Y-axis will be automatically switched into the default
“dBm” when the scale type is changed from Lin to Log.

In Lin scale type: the Y-axis denotes the linear coordinates, the value shown at
the top of the grid is the reference level and the bottom of the grid shows 0 V. The
grid size is 10% of the Reference level and the Scale/Div is invalid. The unit of
Y-axis will be automatically switched into the default “Volts” when the scale type
is changed from Log to Lin.

Other than as mentioned above, the unit of Y-axis is independent of the Scale
Type.
2.1.3.6 Units
Sets the unit of the Y-axis to dBm, dBmV, dBuV, Volts or Watts. The units dBm, dBmV,
and dBuV are for Log scaling; Volts and Watts are for Linear scaling. The default is
dBm.
