Marker
Marker is used to get the information about a specific trace. Six markers can be set on the display and each
marker can be used independently. The X and Y coordinates of the trace are displayed when the 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 one and six.
◼
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.

Sets the X coordinate of the active marker as selected.

Center:
Sets the frequency of the active marker to the center frequency of spectrum
analyzer.

Start:
Sets the frequency of the active marker to the start frequency of spectrum
analyzer.
-

→
Stop:
Sets the frequency of the active marker to the stop frequency of spectrum
analyzer.
◼
Frequency Count:
This Frequency Count is used when a highly accurate reading of the frequency
is needed for the active marker on the signal. The measurement sweeps get significantly slower
because the instrument runs the measurement of the signal peak with 1 Hz resolution in
background. Toggle this key between
On
and
Off
to enable or disable the frequency count function
for the selected marker.
◼
Noise Marker:
This Noise Marker is used to measure a noise adjacent to a signal by averaging
several data points to calculate the readout for the Noise Marker as if making a measurement using
a 1 Hz bandwidth. Toggle this key between
On
and
Off
to enable or disable the noise marker
function for the selected active marker.
