Delta Markers – DELTA Key
The delta marker.s are used to measure a level or frequency referred to a reference marker. They are
always referenced to the marker whose position was last changed. A delta marker is displayed
as an empty symbol. The reference marker is displayed as a filled symbol.

The DELTA key switches a delta marker on and calls the
menu for its control. If no marker is enabled, MARKER 1 is
automatically activated when the delta marker is switched on.

The DELTA 1 to 4 softkeys are used to enable delta markers 1...4. The
control of the delta markers corresponds to that of the markers. After a delta
marker has been enabled, all entries are now applicable to this marker. The
main marker must be activated anew if its position is to be changed.
The delta marker field on the display screen contains the delta marker
number, the difference frequency from the delta marker to reference marker
and the level difference between the active delta markers and reference
markers.
The indicated differences are, in general, referred to the reference marker. If
the PHASE NOISE or REFERENCE FIXED functions are enabled, the
reference values under REFERENCE POINT are applicable.
