After the reference line has been shifted by entering REF VALUE –10 dB, depar-
tures from the nominal value can be displayed with high resolution (e.g. 1 dB / Div.).
The absolute measured values are still displayed, in the above example, 1 dB below
nominal value (reference line) = 11 dB attenuation.
