Use Gate
Enables FFT gating and shows the gate.
If enabled, the "Gate Definition" settings are used.
If disabled, the relation between the record length and the RBW can be defined man-
ually instead.
When a gate is used, the RBW is adapted, if necessary. The smaller the gate, the
higher the RBW.
For details, see Chapter 9.1.1, "Fundamentals of FFT analysis", on page 398.
Gate Definition
Defines the gate settings for FFT gating.
Zoom coupling ← Gate Definition
Zoom coupling is available if a zoom is defined. As long as "Zoom coupling" is
enabled, the gate area is defined identically to the zoom area - if you change the zoom,
the gate changes as well.
If several zoom diagrams are defined, select the zoom diagram to be used for gating.
The "Start" and "Stop" values of the gate are adjusted accordingly.
Zoom coupling can be set for measurement gates, FFT gates, and search gates. The
zoom must be defined on the diagram that contains the signal source of the measure-
ment, FFT, or search.

Mode ← Gate Definition
Defines whether the gate settings are configured using absolute or relative values.
"Absolute"
The gate is defined by absolute start and stop values.
"Relative"
The gate's start and stop values are defined by a percentage of the
value range.
