4.11. Y-axis Units
Set the unit of Y-axis to dBm, dBmV, dBuV, Volts or Watts.
dBm, dBmV, dBuV are uint for Log scaling, but Volts and Watts are unit for Lin scaling. Defualt
uinit is dBm.
4.12. Ref Offset
Assign an offset to the reference level to compensate for gains or losses generated between the
measured device and the analyzer. Then the level of external amplitude tansformer input can be
taken as reference for measured signal level.
Key points:
 The change of this parameter will not change the position of curve on screen, but change the
read out of the reference level and marker amplitude.
 You can modify this parameter by numeric keys. For more details, please refer to “Parameter
Input”.
