Behavior
The m aximum level of adjustment determines how far Autofit will search for the best fit to minimize hits.
For example, if you set the Vertical Maximum to 10% per division, Autofit searches up to and including
10 per
cent of the vertical divisions for the best fit. Autofit minimizes hits by aligning the signal within
the mask.
Clic
king Masks replaces the Mask Configuration Autofit control window with the Mask Testing control
window.
NOTE. The interaction between Autofit and Persistence can affect the display of persistence data. Autofit
moves the waveform vertically and/or horizontally to reduce the number of hits within a given mask. If
either infinite or variable persistence is enabled these movements will clear any persistence data. If Autofit
makes frequent adjustments, there can be little or no persistence data.
