Defining the bargraph scale
The scale of the bargraph is defined by the reference level and level range.
The reference level is the maximum power level that the bargraph displays. You should
set the reference level in a way that the signal level does not exceed the reference
level and high enough so that the signal does not disappear in the inherent noise.
1. Press [AMPT] key.
2. Select "Ref Level" softkey.
The R&S Spectrum Rider opens an input field to define the reference level.
3. Define the reference level that best fits the measurement.
In the default state, the reference level corresponds to the level at the right of the
bargraph.
The reference level position is shown by a triangle in the bargraph scale label.
