Scope Multimeter Saving and Reviewing Scope / Multimeter Data Files
NOTE:
i
Zoom playback controls are identical to the standard playback controls used when reviewing data
files, with the following exception:
Skip Forward / Skip Back control icons - (press once) moves multiple steps relative to set
magnification level (e.g. 2X setting, moves 2 steps; 16X setting, moves 16 steps)
Additional information on playback control icons are described in Scope Multimeter Control Icons ‚
on page 40 and Common Toolbar Control Icons ‚ on page 13.
When the Zoom icon is selected the display defaults to the "Max" magnification level and a
dropdown scroll menu displays. The dropdown menu allows you to select the display
magnification level from a range of 1X to 256X. The "Max" (maximum) option displays all data
captured on one screen (
Figure 5-37 ).
Figure 5-37
“Max" Magnification Level - displays all captured data
When zoom levels of 2X and higher are selected, a Zoom cursor (vertical dashed line)
(
Figure 5-37 ) displays onscreen. The cursor is used to quickly mark and navigate to points of
interest or glitch in a captured waveform.
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 5-38 shows examples at 32X and 64X with
the Zoom cursor positioned in the area of a signal drop glitch.
NOTE:
i
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, then lower the
zoom level to 8X or 2X to review in detail.
