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.
