Affects: Y-axis of Y-vs-X trace amplitude graphs
Normally, the Y-axis trace amplitude reference is taken from a single point in each frame. By setting this parameter to a larger value, you can cause the program to search an area of the length you specify, from the given "Second trace ampl. ref", for a maximum or minimum level. This level will be used as the reference level which is subtracted from the sample level for the Y-axis.
