Sweep
Segmented Accesses the segmented sweep function and its editor.
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 (
Sweep, Segmented, Modify, Edit)
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.

Sweep
NOTE This feature is only available on ESA-E series analyzers (E4401B,
E4402B, E4404B, E4405B, E4407B) with firmware revision
≥ Α.05.00.
Segmented On Off
Turning segmented sweep on (Sweep, Segmented, Segmented (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.
NOTE Frequency, Scale Type (Log) is not available when Segmented (On) is
selected.
