When you deactivate the zoom display, the previous display is restored.
4.3.2 Zooming for Details
The zoomed area and its position can be configured numerically or using the rotary knobs.
To display a zoom diagram
► Press the ZOOM key.
The key lights up and two windows are displayed: the original signal vs. time at the
top, the zoom at the bottom.
To deactivate the zoom display
► Press the ZOOM key again, or press the "Zoom Off" softkey in the "Zoom" menu to
close the zoom window.
The ZOOM key is no longer illuminated and the previous display is restored.
To configure the zoom area numerically
1. Press the "Zoom Time Base" softkey to define the scaling for the time base in the
zoom diagram in seconds per division. The scaling is indicated by "Z" in the infor-
mation bar above the zoom diagram and determines the width of the zoom area that
is displayed in the zoom diagram (10 divisions * scaling per division).
2. Press the "Zoom Time" softkey to define the offset of the trigger point to the reference
point 0s in the zoom diagram. The offset is indicated by "Tz" in the information bar
above the zoom window and determines the position of the zoom area.
The zoom area is indicated by white lines in the original Y(t)-window. The zoom win-
dow displays the data in the defined zoom area from the main time base in greater
detail.
