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. Swapping the start and stop value
(reversal of the sweep direction) therefore produces the reciprocal value. The closer
the numeric value is to 1.0, the more sweep steps will be performed.
(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.
