"Dwell File" The sweep stepping is time-controlled in individually set intervals, i.e.
a new sweep point is set automatically if the associated time has
expired, irrespective of whether the measurements activated in the
analyzer have been completed. A new measurement is started at the
same time.
The file containing the list of dwell times can be specified by the user
in the parameter field below.
This setting makes it possible to specify not only a separate dwell
time for each sweep point, but also an individual measurement time.
It should only be chosen if the internal analyzer is not in use, mea-
sured values are not needed or the dwell time of a sweep point is lon-
ger than the associated measurement time.
The dwell list is processed in the direction of the sweep, i.e. starting
with the last entry in the case of a downward sweep. The specified
dwell time will thus be maintained for each sweep point even if the
sweep direction is changed.
Note: If measured values are also required in this mode, the individ-
ual measuring time should be determined and entered to attain a high
sweep speed. This applies particularly to frequency sweeps using
automatic measurement time. If the dwell-time list is shorter than the
sweep list or the length of the sweep axis, the last dwell time in the
list is applicable for all remaining sweep points.

5.9.5 Linear and Logarithmic Sweep
Both linear and logarithmic sweeps are calculated automatically from user entries.
For this purpose, the user must specify:
●
the spacing type (logarithmic or linear)
●
either the number of points ("Points") or the step size ("Step")
