Analysis and Processing of Result
Analyze trace bandwidth
8. Analysis and Processing
of Result
Bandwidth: Indicates the interval of sweep parameter values at two
cutoff points (width = interval between sub-markers 2 and
3 in Figure 8-15). This definition does not depend on the D
marker mode.
Center: Indicates a midpoint between the sweep parameter values
at two cutoff points (center = sweep parameter value at the
position of sub-marker 1 in Figure 8-15). It serves as a
relative value with reference to the fixed D marker only
when the fixed D marker is present.
Q Indicates value Q obtained from two cutoff points
(Center/Width).
Peak: Indicates the measurement parameter value at the position
of the main marker (marker 0). However, it indicates a
relative value with reference to the fixed D marker only
when the fixed D marker is present. When the main
marker is moved to the peak by using the peak search
function, that peak is displayed at this position.
DL Indicates the length of the sweep parameter from the
sweep center value to the cutoff point on the left.
However, it indicates the length of the sweep parameter
from the sweep parameter value of the fixed D marker to
the cutoff point on the left only when the fixed D marker is
present.
DR Indicates the length of the sweep parameter from the
sweep center value to the cutoff point on the right.
However, it indicates the length of the sweep parameter
from the sweep parameter value of the fixed D marker to
the cutoff point on the right only when the fixed D marker
is present.
