(dBm) in Log scale type when the scale type is changed from Lin to Log.
 In Lin scale type, the Y-axis denotes the linear coordinate; the values shown
at the top of the grid and the bottom of the grid are the reference level and 0
V respectively. Each grid represents 10% of the reference level and 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 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.
