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
