Marker Setup
Marker
Marker is used for marking the point on the trace. Reads the amplitude, frequency, or
distance of a certain point on the trace via marker.
Remarks:
⚫
In VNA mode, each trace window provides 8 markers, and only a single marker
or one pair of markers can be turned on each time.
⚫
Before enabling the marker in a certain trace window, you need to set the
current trace first.
⚫
In the Marker menu, you can use the numeric keys, the knob, or the arrow keys
to modify frequency or distance; to view the readout of different points on the
trace. You can also use the touch screen to do the above things.
Selected Marker
In VNA mode, each trace window provides 8 markers. By default, Marker 1 is
selected under "Selected Marker".
After you select a marker, you can set parameters such as the marker mode and the
marker frequency. The readout of the currently activated marker at the marker point
will be displayed in the measurement result bar at the upper-left corner of the
screen.
Marker Mode
Sets the type of the marker. The available marker modes include Position, Delta,
Fixed, and Off.
1.
Position
It is used to measure the X (Frequency or Distance) and Y (Amplitude) values of
a certain point on the trace. When "Position" is selected, a marker indicated by a
number ("1") appears on the trace.
Remarks:
⚫
If no active marker exists currently, a marker will be enabled at the X-axis
center of the current trace.
⚫
The readout resolution of the X-axis (frequency or distance) is related to the
span. To obtain a higher readout resolution, reduce the span.
2.
Delta
It is used to measure the difference between "reference point" and "certain
point on the trace": X (frequency or distance) and Y (amplitude) value. When
"Delta" is selected, a pair of markers appears on the trace: Reference Marker
(marked by "X") and the Delta Marker (marked by "
△
").
