By selecting a number of sweep points greater than 401, you are

optimizing frequency resolution and accuracy while accepting a reduced
measurement speed. In addition to sweep points, the span, resolution
bandwidth, video bandwidth, average detection and center frequency
will also affect measurement speed.
This function is not available when signal identification is on

value for points.
This feature is not available in the E4403B, E4408B, or E4411B (ESA-L
Series). The number of points per sweep for these models is always set
to 401.

Segmented
Segmented sweep is a method in which you can select multiple
frequency bands (a maximum of 32), specify their parameters
individually, and display them as a single trace. This function of the
analyzer results in faster measurements and provides greater detail
and resolution in particular bands of interest. To set the parameters of
individual segments, go to the editor (
and refer to the parameter key descriptions below. For measurement
examples of the segmented sweep function, refer to the Agilent ESA
Spectrum Analyzers Measurement Guide.
Key Access:
This feature is only available on ESA-E series analyzers (E4401B,
NOTE
E4402B, E4404B, E4405B, E4407B) with software revision ≥ Α.05.00.
Segmented On Off
Turning segmented sweep on (
displays each sweep segment from left to right in order of increasing
start frequency. When segments have the same start frequency, the
segments are displayed in order of increasing stop frequency.
Overlapping segments are acceptable. (Note however; the reference
marker for a marker delta will be displayed in the first segment).
Segments are demarcated by vertical lines. The width of a given
segment is determined by the ratio of the number of sweep in the
segment to the number of sweep in the total trace. For example, if there
are five segments with 101 sweep each (505 total), each segment
occupies 20% of trace. If you increase the number of in one of the
segments to 404 (808 total), that segment will occupy half of the trace;
the other four segments, 12.5% each. You can define up to 32 segments
with a total maximum number of sweep equal to 8192.
