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:
The conversion relationships between units are as follows.

Wherein,
R
denotes the reference resistance.
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 on the screen.
You can modify this parameter using the numeric keys. For more details,
please refer to “Parameter Setting”.
