Fine Adjustment Using An Existing Or Preset Characteristic - R&S N 8000 Series System Manual

1. Set another onset point in the upper level range >25%.
2. Optimize the shoulder distance by alternately setting the amplitude and phase regula-
tors with the aid of the slopes of point 2.
The slopes will then point in the opposite direction than at Point 1.

Fine Adjustment Using an Existing or Preset Characteristic

If the required data is not or is no longer observed to be in an existing or factory-set precor-
rection characteristic, the precorrection does not necessarily have to be readjusted.
An adjustment to the true amplifier characteristic can be obtained by changing individual
interpolation points. The range with the greatest effect can be determined by slightly chang-
ing individual interpolation points. Changing the interpolation values in this range will most
probably produce the desired result. Changes should be made in small steps, preferably
with the aid of the Navigator window. A change must be undone if it does not result in an
improvement.
