In spectrum mode, the R&S ESR shows the following settings:
Ref Level Reference level
Att RF attenuation level.
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.
Compatible Compatible device mode (FSP, FSU, default; default not dis-
played)
Mode Indicates which sweep mode type is selected:
●
"Auto FFT": automatically selected FFT sweep mode
●
"Auto sweep": automatically selected swept sweep mode
●
