Negative reference values < -1.0E-12 are computed using their magnitude, that is, they
are made into positive values.
As a result, trace displays in the referenced unit dBr, for instance, at a reference value
of 0.0 V have very high values for the upper limit, since the trace data is computed
internally using the reference value 1.0E

Normalize
If a referenced unit (e.g. dBr or V/Vr) and a floating reference value, as in Reference =
Meas Ch1, Meas Ch2, Gen Track, or a reference trace held in a file, as in "File" or "File
Intern", are used, the displayed trace is normalized with the aid of the above by shifting
the whole curve, that is, multiplying it by the normalization value.
The normalization value is transferred to all scan data sets; the same normalization
value therefore applies to all scans.
