There are different ways to initiate and configure the zoom function:
Graphically by drawing and moving the zoom area on the touch screen – a very
quick and simple method for hardware zoom and zoom diagrams
Numerically by entering x- and y-values in a dialog box – a more precise method
which can be used to optimize a graphically defined zoom
With the numeric method there are two ways of defining the zoom area:
Specifying start and stop values for the x- and y-axes; the acquired data within
those values is zoomed.
Fig. 4-1: Numeric zoom using start and stop values
Specifying the x- and y-
position of the centerpoint of the area plus a range for
the x- and y-axes; the area defined by that centerpoint and the ranges is zoomed.
Fig. 4-2: Numeric zoom using position and range
Evaluation gates - available histogram areas, masks, and measurement gates - can be
displayed in zoom diagrams to simplify the graphical gate adjustment on the touch
screen. See: "Show evaluation gate(s) in zoom" on page 98.
