"activated"
The unit selected in the analyzer is used for the measurement data
displayed on the y-axis and for the displayed top, bottom and limit
values.
It is displayed in gray (cannot be accessed) next to the checkbox and
also on the y-axis of the graphical display.
If a logarithmic unit (dBu, dBV, dBr, dBm or dBFS) appears here, the
parameter field below (Spacing) cannot be accessed and its parame-
ter is set to Lin (it would be pointless to display measured values with
a logarithmic unit on an axis with logarithmic spacing).
Figure 5-26: Here rotated by 90°.
The unit which appears here depends on the parameter selected
under Trace
A or Trace B, e.g. Level Ch1, Phase Ch1 and on the
analyzer instrument, e.g. "Analog" or Digital Audio.
In the event of changing between similar units (e.g. dBu. dBV, dBm,
or dBr), a new value is computed for the subsequent 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.
"deactivated"
The unit can be user-selected from the list of available parameters.
If a logarithmic unit (dBu, dBV, dBr, dBm or dBFS) is selected here,
the parameter field below (Spacing) cannot be accessed and its
parameter is set to Lin (it would be pointless to display measured val-
ues with a logarithmic unit on an axis with logarithmic spacing).

Unit
This parameter field without the "Unit Fnct Track " is displayed only for the graphic
system Waveform, since this additional measurement function is independent of a
function setting in the analyzer and even delivers measurement results when the mea-
surement function is turned off. Therefore tracking the unit of the measurement func-
tion is meaningless.
The list of units offered at this point is dependent on whether the analog or digital ana-
lyzer is selected. The unit can be user-selected from the parameter list.
