Sweeping a Plural Number of Sweep Areas under Different
Conditions at One Time (Segment Sweep)
When linear sweep or log sweep is selected as the sweep type in frequency sweep, certain
measurement conditions like the point averaging factor and the oscillator level are uniform
over the entire single sweep. Consequently, it is not possible to change such settings for a
particular area.
In segment sweep, on the other hand, a plural number of frequency areas, which are called
“segments,” can be individually set by users. In this case, certain measurement conditions
(i.e., number of points, point averaging factor, source unit/oscillator level, DC bias
mode/level/limit) can be set for each segment, and the entire series of such segment setups
can be sequentially executed as a single sweep (Figure 3-6).
By using this feature, it is possible to take a sweep measurement in only the desired area
and to skip the frequency areas that you do not need to measure. It is also possible to set
optimal measurement conditions for each designated segment. For example, you can
increase the point averaging factor and number of points for segments that require
measurements with higher stability and more accurate frequency resolution (as resonance
point). For segments without such stringent measurement requirements, you can set the
conditions to enable high-speed measurement.
