to define the scope of the measurement. All these settings are described in more

The Analyzer Level softkey controls the level in the RF input signal path and pro-
vides the trigger settings for the current measurement.
The input level and trigger settings are general settings and therefore also provided

Control – Trigger) on p. 4.72 ff.

The Reference Level hotkey defines the reference level.
The reference level defines the upper edge of the diagram. It is generally different
