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.
⚫ Two ways to enable a certain point as the reference:
a) Open a "Normal" marker and locate it onto a point and then
switch the marker type into "Delta", creating a new reference,
then you can modify the location of the delta point to achieve the
delta measurement.
b) Open a Delta Marker and place it onto a point, then reselect
the Delta menu to locate the marker you opened onto this points,
then you can modify the location of the delta point to achieve the
delta measurement.
