2.1.3.5 Scale
Set the logarithmic units per vertical grid division on the display. This function is only available when the
scale type is set to “log”.
● By changing the scale, the displayed amplitude range is adjusted.
● The Minimum range: Reference level –10 × current scale value.
● The Maximum range: The reference level.

2.1.3.6 Scale Type
Set the scale type of the Y-axis to Lin or Log. The default is Log.
● In Lin mode, the vertical Scale value cannot be changed. The Display area is set for reference level
of 0%.
● In Log scale type, the Y-axis denotes the logarithmic coordinate. The value shown at the top of the
grid is the reference level and each grid represent the scale value. The unit of Y-axis will
automatically switch to the default unit (dBm) in Log scale type when the scale type is changed
from Lin to Log.
● In Lin scale type, the Y-axis denotes the liner coordinate; the values shown at the top of the grid
and the bottom of the grid are the reference level and 0 V. The scale setting function is invalid. The
unit of Y-axis will automatically switch to the default unit (Volts) in Lin scale type when the scale
type is charged from Log to Lin.
2.1.3.7 Ref Offset
Assign an offset to the reference level to compensate for gains or losses generated between the device
under measurement and the analyzer.
The change of this value changes both the reference level readout and the amplitude readout of the
marker; but does not impact the position of traces on the screen.
