The minimum sweep time depends on the number of measurement points, the mea-
surement bandwidth, the delay time before each partial measurement and the number
of partial measurements required for each measurement point. The analyzer estimates
this time, based on the current measurement settings.
If the "Stop Time" is smaller than the estimated minimum sweep time, the entered
value is increased automatically.
Equidistance of sweep points
The analyzer tries to keep the time intervals between any two consecutive time sweep
points equal: The time sweep samples are equidistant. Equidistance also holds for
sweeps which range over several channels.

Seg X-Axis
Scales the x-axis for a segmented frequency sweep:
●
In "Freq based" mode, the x-axis covers the frequency ranges of all sweep seg-
ments, including possible gaps between the segments. Equal frequency spacings
correspond to equal distances on the x-axis.
●
In "Point based" mode, the x-axis shows all sweep points with equal spacings.
Gaps between sweep segments are minimized; no diagram space is "wasted" on
unused frequency ranges. Point-based mode is indicated in the channel line.
The example below shows a segmented frequency sweep with two segments. The first
segment ranges from 1 GHz to 1.4 GHz; the second segment from 2 GHz to 3 GHz.
Both segments contain 11 sweep points. In point-based mode (lower diagram), all
sweep points are equidistant.
