ZOOM
|
|
The
zoom feature allows waveforms to be expanded, compressed and positioned in
both vertical and horizontal axes. Allows precise comparison and
study of fine waveform detail without affecting ongoing
acquisitions. When used with Hi-res or Average acquisition modes,
Zoom provides an effective vertical dynamic range of 1000 divisions or 100
screens.
