Oscilloscope Reference Using the MultiZoom feature
Using the MultiZoom feature
Use the instrument MultiZoom feature to magnify an acquisition vertically, horizontally, or in both
dimensions to let you see the fine detail in your signals without changing the acquisition parameters
(sample rate
, record length, and so on). For example, to temporarily expand the front corner of a pulse to
inspect its aberrations, push the front-panel MultiZoom button to expand it horizontally and vertically.
To help you u
se Mulitzoom effectively, consider how it operates on waveforms:
When zooming vertically, the instrument expands up to four zoomed areas at one time. The zoomed
areas can a
ll be on the same waveform or they can be on different Channel, Mat h or Reference
waveforms. Each zoomed area has its own v ertical position and factor.
When zoom
ing horizontally, the Zoom Source is either the acquisition waveform or one of the zoomed
areas.
When zoo
ming either horizontally or vertically, Zoom expands or contracts the waveform by the
Zoom Factor.

Automatic m easurements
All channel, reference, and math waveforms can serve as sources for automatic measureme nts . Some
measurements, suc h as Delay and Phase, require two sources.
NOTE. Automatic measurements are not available on digital channels.
The following automatic measurement categories are available:
Amplitude (see page 270)
T
ime
(see page 273)
More (see page 282) (miscellaneous)
Histogram (see page 290)
Communication (see page 278)
Click the category for a list of the measurements that you can choose from in each category.
The instrument can take and update up to eight measurements at one time . You can apply measurements
to any combination of sources. For example, you can take all eight measurements on Channel 1, or you
724 DSA/DPO70000D, MSO/DPO/DSA70000C, DPO7000C, and MSO/DPO5000 Series
