Glossary
Waveform memory A waveform
memory is a convenient, nonvolatile,
waveform storage area. A waveform
memory contains a single waveform
record along with the vertical and
horizontal scaling factors for that
waveform.
Zooming Zooming is used when
the acquisition is in the stopped
mode. Zooming either expands or
compresses the acquired waveform
on the horizontal axis of the display.
It is controlled by the time base
time/div controls for expansion or
compression of a single-shot wave-
forre in the real-time mode.
Decreasing time/div expands the
waveform and is referred to as
"zooming in." Increasing time/div
compresses the waveform and is re-
ferred to as "zooming out."
