Note: The number of points on the z-axis (20 maximum) is copied to the Sweep Graph
Config panel as "History" if it is larger than the value specified there and the X-Source
of the respective window is set to Sweep.

Step
Used to enter the (linear or logarithmic) step size for the sweep parameter set in the
parameter field above. Only visible for activated generator sweep system if "Lin Steps"
or "Log Steps" is set for "Spacing". It is set separately for each sweep parameter.
The entry range is limited automatically so that at least one and at most 1023 single
steps exist (corresponding to 1024 sweep points).
With linear step, the size of the step must always be entered, i.e. the numeric value is
positive even if the start value is greater than the stop value. The physical unit is the
same as that used when specifying "Start" and "Stop".
(Example for lin. frequency sweep)
With logarithmic step, the factor must be entered by which each sweep point is to be
multiplied in order to move to the next sweep point. The logarithmic step size of level
sweeps can also be specified in dB. Swapping the start and stop value (reversal of the
sweep direction), therefore produces the reciprocal value and changes the sign of the
dB value. The closer the numeric value is to 1.0 or 0
dB, the more sweep steps are
carried out.
(Example for log. upward sweep)
Note: Since the last step of the sweep is automatically adapted such that it corre-
sponds exactly to the stop value, it may deviate by max. 50 % from the selected step
size. If this is to be avoided, either the start/stop value must be corrected accordingly
or the sweep spacing must be set using the "Points" parameter.
Note: The number of points on the z-axis (20 maximum) – determined by Start, Stop
and Step – is copied to the Sweep Graph Config panel as "History" if it is larger than
the value specified there and the X-Source of the respective window is set to Sweep.

5.9.6 List sweep
With list-controlled sweeps, any sweep axis can be defined. The sweep points may be
any distance apart, but must be in ascending or descending order ("Random sweep").
