Fig. 4.24 Measurement with REF VALUE -10 dB and REF VALUE POSITION 50%
After the reference line has been moved by entering a REF VALUE of –10 dB the
deviation from the nominal power level can be displayed with high resolution (e.g.
1 dB/div). The power is still displayed in absolute values, which means that in the
above example 1 dB below the nominal power (reference line) = 11 dB attenuation.
