ESIB
Receiver - Delta Markers
DELTA MKR
ABS REL
The DELTA ABS REL softkey switches between relative and absolute entry
modes for the delta-marker frequency.
REL
The delta marker frequency is entered relative to the reference
marker. In this case, the entry mode for the delta-marker
frequencies is also relative.
ABS The entry of the delta-marker frequency is in terms of absolute
frequency.
The default setting is REL.
IEC/IEEE bus command
:CALCulate:DELTamarker:MODE ABS | REL
ALL DELTA
OFF
The ALL DELTA OFF softkey switches off all active delta markers and any
associated functions (e.g. REFERENCE FIXED).
IEC/IEEE bus command
:CALCulate:DELTamarker:AOFF
REFERENCE
FIXED
The REFERENCE FIXED softkey enables/disables relative measurements
with respect to a fixed, measurement-curve-independent reference value
(REFERENCE POINT).
The information in the delta-marker field on the display screen is referenced
to this fixed reference point. For the generation of the marker lists using
MARKER INFO list, the delta markers are also output relative to a fixed
reference. In the lists, the REFERENCE POINT is tagged by the number of
the reference marker (only one enabled)
When REFERENCE FIXED is enabled, the current settings of the reference
marker become the reference points. If no marker is active, MARKER 1 (with
peak search) is activated. After transferring the reference values, all markers
are deleted, and the active delta marker is set to the position of the reference
point. Additional delta markers can be switched on.
The reference point can be subsequently changed
1. by shifting it in the REFERENCE POINT sub-menu.
2. by starting a search:
In the MARKER NORMAL menu the REF POINT is handled as a reference
marker (even though it is not bound to the measurement curve). This
means, that it will be shown as enabled and can also be changed in
position. The co-ordinates of the REF POINT are overwritten by the marker
values (they lie, by definition, on the measurement curve). Thus, it is
possible, even for an enabled REFERENCE FIXED, to define a new
reference point with search functions.
