3 WLAN Mode
3.9 Spectral Flatness Measurement
Couplings The selected marker becomes a delta marker if not already in delta mode.
State Saved Not Saved in instrument state.
Marker Delta
Pressing this button is exactly the same as pressing the “Delta” selection on the
"Marker Mode" on page 1480 radio button on the Settings tab. The selected marker
becomes a Delta Marker.
If the selected marker is already a Delta marker, the reference marker is moved to
the current position of the selected marker, thus resetting the Delta to zero.
The control is duplicated here in the Peak Search Menu to allow you to conveniently
perform a peak search and change the marker’s control mode to Delta without
having to access two separate menus.
3.9.7.4 Properties
The controls on the Properties tab are used to set certain properties of the selected
marker.
Marker X Value
The Marker Frequency control is the fundamental control that you use to move a
marker around on the trace. This is the same as the "Marker X Value" on page 1478
on the Settings tab.
Relative To
Selects the marker to which the selected marker is relative (its reference marker).
Every marker has another marker to which it is relative. This marker is referred to as
the “reference marker” for that marker. This attribute is set by the Marker,
Properties, Relative To. The marker must be a Delta marker to make this attribute
relevant. If it is a Delta marker, the reference marker determines how the marker is
controlled and how its value is displayed.
A marker cannot be relative to itself.
