Behavior
Use the Z
oom Setup control window to magnify (zoom in on) a waveform without changing the main
acquisition parameters. Use Zoom when you want to temporarily look at details of a waveform.
If the z
oom areas are unlocked, the Horizontal Position and Factor controls affect only the selected zoom
area. The Horizontal Position and Factor will affect all zoom areas that are locked together, such that a
change to one zoom area will change the horizontal position and factor of all the locked zoom areas.
On the Vertical Zoom tab, the Scale and Factor controls only affect the selected waveform.
