Invalid settings
A bullet next to the hardware setting indicates that user-defined settings are
used, not automatic settings. A green bullet indicates this setting is valid
and the measurement is correct. A red bullet indicates an invalid setting that
does not provide useful results.
It is the user's responsibility to remedy such a situation.
Editing settings in the channel bar
All settings that are displayed in the channel bar can easily be edited by
touching the setting in the display (with a finger or mouse pointer). The cor-
responding (edit) dialog box is displayed where you can edit the setting.
In spectrum mode, the R&S FSVA/FSV shows the following settings:
Ref Level Reference level
m.+el.Att Mechanical and electronic RF attenuation that has been set.
Ref Offset Reference level offset
SWT Sweep time that has been set.
If the sweep time does not correspond to the value for automatic
coupling, a bullet is displayed in front of the field. The color of the
bullet turns red if the sweep time is set below the value for auto-
matic coupling. In addition, the UNCAL flag is shown. In this case,
the sweep time must be increased.
RBW Resolution bandwidth that has been set.
If the bandwidth does not correspond to the value for automatic
coupling, a green bullet appears in front of the field.
VBW Video bandwidth that has been set.
If the bandwidth does not correspond to the value for automatic
coupling, a green bullet is displayed in front of the field.

played)
