Scope / Multimeter Capturing Data
36
NOTE
It is important to remember that whatever sweep setting you used during data
capture is what the 1X zoom level will show.
The active zoom options (1X to 512X (Max)) that are selectable are dependent on
the amount of data stored in the buffer. Less data captured = less zoom options.
More data captured = more zoom options.

Figure 3-37
“Max" Magnification Level - displays all captured data
When zoom levels of 2X and higher are selected, a Zoom cursor (vertical dashed
line) (
Figure 3-37
) displays onscreen. The cursor is used to quickly mark and
navigate to points of interest or glitch in a captured waveform.
NOTE
To quickly identify a glitch in a pattern, it may be easier to initially view the
waveform at a higher magnification level (e.g. 256X or "Max") to display the
entire captured waveform, find the area of interest and then lower the zoom
level to 8X or 2X to review that area in detail. See
Zoom Example on page 37
.
The Zoom cursor can be used to mark the approximate position of a glitch and can
be manually dragged onscreen to the desired position. The new cursor position will
be centered on the screen when a lower magnification level is selected.
Figure 3-38
shows an example at Max with the Zoom cursor positioned in the area
of a signal drop glitch.
