In marker delta mode, a reference marker is placed at the active marker
position. All marker values are then displayed in reference to this delta
marker. When the amplitude of the measurement trace changes, the
reference marker value also changes. The delta marker is represented by
a triangle pointing up (A) with a delta symbol (A) below it rather than a
number.
Limit testing can be performed on delta amplitude and delta frequency using
specific markers. See "To Use Marker Limit Functions, * later in this chapter.
