If a logarithmic unit (dBu, dBV, dBr, dBm, dBFS) is selected, or a linear unit in which
negative numbers can occur (e.g. ∆V, ∆W), the following parameter field Spacing is
displayed as not user-accessible and its parameter is set to Lin since it makes no
sense to display measured values with a logarithmic unit or negative values on a loga-
rithmically scaled axis.
In the event of changing between similar units (e.g. dBu. dBV, dBm, dBr), a new value
is computed for the following parameter fields
"Top", "Bottom",
"Main Grid Steps",
"Limit Lower Value", "Limit Upper Value",
"Limit Shift Parallel", "Limit Shift Symmetrical";
in the event of changing between different units (e.g. dBV, W), a value entered earlier
is retrieved.

Unit Auto
Used to determine whether the unit label displayed on the y-axis for Trace A or Trace
B is the same as the unit set in the "Unit Funct Track" or "Unit" parameter field or
whether it can be user-selected.

"activated"
Used to determine whether the unit label displayed on the y-axis for
Trace
A or Trace B is the same as the unit set in the Unit Funct
Track or Unit parameter fields and are therefore generated automati-
cally by the R&S UPP.
