marker is placed on any position of the trace. The position displaying the marker’s X and Y
coordinates may be slightly different for each measurement mode and refer to the description of each
measurement. There are three different marker types available: Normal, Delta, and Delta pair. Marker
position can be set manually by entering numeric values (frequency) when one of the marker types is
selected.
SELECT MARKER:
Selects an active marker whose position can be changed with the rotary
knob or the arrow keys. The assigned number of the active marker is displayed in the
Select
Marker
menu box and the active marker number is also displayed right next to the active marker
on the trace when the
Marker View
is set to
On
.
MARKER VIEW:
Displays the selected marker on the screen or hides it. When the
Marker View
is turned off and then on again in the same measurement mode, markers appear at the previous
positions. If a measurement mode is changed, markers are not restored to their previous positions.
NORMAL:
This Normal marker type provides the reading of a marker position on the trace along
with the marker number between 1 and 6.
DELTA:
This Delta marker type is associated with a Normal marker. A Normal marker must be set
before a Delta marker is set. When the Delta marker is set, the position set by the Delta marker
becomes the reference position of the Normal marker and the marker’s X and Y values displays
the difference compared with the Delta marker.
DELTA PAIR:
This Delta Pair marker type is associated with a Normal marker. A Normal marker
must be set before a Delta Pair marker is set. When the Delta Pair marker is set, the position set
by the Delta Pair marker becomes the reference position of the Normal marker and the marker’s X
and Y values displays the difference compared with the Delta Pair marker. The reference position
will be varied in accordance with trace change.
MARKER ALL OFF:
Turns all the markers the screen off. When the Marker View is selected for
those markers, the instrument displays those markers back at the previous position. If a
measurement mode is changed, current settings are not restored.
MARKER

Sets the X coordinate of the active marker as selected.
MARKER
CENTER:
Sets the frequency of the active marker to the center frequency of
spectrum analyzer.
MARKER
START:
Sets the frequency of the active marker to the start frequency of
spectrum analyzer.
MARKER
STOP:
Sets the frequency of the active marker to the stop frequency of spectrum
analyzer.
