“Volts” in Lin scale type when the scale type is changed from Log to Lin.
 The scale type does not affect the unit of Y-axis.
Units
Set the unit of the Y-axis to dBm, dBmV, dBuV, Volts or Watts. Wherein, dBm,
dBmV, and dBuV are for Log scale; Volts and Watts are for Linear scale. The
default is dBm.
Key Points:

Ref Offset
Assign an offset to the reference level to compensate for gains or losses generated
between the device under measurement and the analyzer.
Key Points:
 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 the curve
