Sensitivity of the measurement. See
●
Measurement Bandwidth ("AF In BW")

For ILS or VOR signals: the modulation of the selected carrier ("AM Demod", "AM
Demod Offset" (low IF mode), "VOR Subc. AM", "VOR Subc. FM"), see
from numeric to graphical results"
Generally, each mode is configured individually. When you switch modes, the most
recently defined settings for that mode are applied.
However, graphical results can also be displayed directly from the measurement
modes with numeric results. In this case, the settings for the current mode are applied
to the graphical results.
If the original measurement mode analyzes multiple carriers, you must select the car-
rier for which you want to see the graphical results when you switch the mode.
