5.14 [Marker]
The marker appears as a rhombic sign (shown below) for identifying the point on the trace. We can easily readout the
parameters of the marked point on the trace, such as the amplitude, frequency and sweep time.
Key points:
• The analyzer allows for up to three groups of markers to be displayed at one time, but only one pair or one single marker
is active every time.
•
You can use the numeric keys, knob or direction keys to enter the desired frequency or time when any marker type menu
is active, so as to view the readouts of different points on the trace.
5.14.1 [Marker 1 2 3 4 5]
Selects one marker, the default is Marker1. And place the frequency scale at the center of the trace. If the frequency
difference is activated, this softkey changes to the menu under the [Difference] function.
If there is already a marker, this command will not produce any operation. If there are already two markers (e.g. in [Difference]
mode), [Marker] changes the active frequency scale to a new single frequency scale. Amplitude and frequency information
can be obtained from the frequency scale (time information when the sweep width is 0Hz), and these values are displayed in
the upper right corner of the active function area and the screen. You can use the numeric keys, the step key, or the knob to
move the active frequency scale.
The marker reads data from the current active track (this track may be track A or track B). If both tracks are active or both
tracks are in static display mode, the frequency scale will read data from track A.
5.14.2 [Trace 1 2 3 4 5]
In the trace measurement, the frequency scale used to activate the traces.
5.14.3 [Normal]
One of the marker types, which is used to measure the values of X (Frequency or Time) or Y (Amplitude) at certain point of
the trace. When selected, a marker will appear with its own digital ID such as “1” on the trace.
Key points:
•
If no active marker exists currently, a one will be enabled automatically at the center frequency of current trace.
•
You can use the knob, direction keys or numeric keys to move the marker. The readouts of the marker will be displayed on
the upper right of the screen.
• The readout resolution of the X-axis corresponds to the span and sweep points. For higher resolution, add sweep points or
reduce the span.
5.14.4 [Delta]
One of the marker types, which is used to measure the delta values of X (Frequency or Time) and Y (Amplitude) between
the Reference point and certain point on the trace. When selected, a pair of markers appears on the trace, which are the
Reference Marker and the Delta Marker. Will be in the active area and the display area of the upper right corner, showing the
amplitude delta value between the two markers and frequency difference. If a single marker already exists, [Delta] will place
a static marker and an active marker to the original position and a single marker position. Use the knob, step key, or number
keys to move the marker. If there are two markers, press [Delta] directly. However, if [Delta] has been activated, press [Delta]
to place the still frequency scale to the active marker. The displayed amplitude difference is expressed in dB, or is the linear
unit in terms of the corresponding scale.
Key points:
• The Reference Marker will be activated at the position of current marker, or else both the reference marker and Delta
Marker will be simultaneously activated at the center frequency location if no marker is active at the present.
• The location of the Reference Marker is always fixed (both in the X-axis and the Y-axis), while the Delta Marker is active.
You can use the numeric keys, knob or direction keys to change the location of Delta Marker.
• The delta of both the Frequency/Time and the amplitude between the two markers are displayed at the upper right of the
screen.
