Looking at waveform details. Use the instrument Zoom function to magnify an acquisition vertically, horizontally, or in both
dimensions to let you see the fine detail in your signals. The MultiView Zoom function affects only the display, not the actual
waveform that is being acquired.
Set up Zoom. The fastest way to set up a MultiView Zoom display is to click (or touch) and drag across the segment of the
waveform that you want to see in greater detail. Then, when you touch or click the on-screen Zoom menu item, that waveform
appears in the Zoom (lower) graticule, while the entire waveform appears in the Acquisition (upper) graticule. Markers in the main
graticule give you position context for what you are seeing in the Zoom graticule.
Another way to set up the MultiView Zoom function is to push the front-panel Multiview Zoom button. Then you can set
parameters in a control window to focus your Zoom waveform on the signal segment of interest.
NOTE. If zoom is on but the readouts are not attached to the zoom controls, press the MultiView Zoom button to attach the
readouts to the zoom controls. Press the MultiView Zoom button again to turn zoom off.
To see more waveform detail you can also use horizontal delay (as described in the previous topic) to focus the acquisition on a
segment of a waveform separated from the trigger event by a significant interval of time. This technique lets you increase the
horizontal resolution (sample faster) on a segment of a signal, even when you cannot trigger on that particular segment.
Zoom function. The Zoom function also allows you to zoom on multiple areas of a waveform or on multiple waveforms
simultaneously. You can lock the zoomed areas and scroll through them together or unlock the zoomed areas and scroll through
them independently.

Triggering, timebase, and horizontal delay
The architecture of an analog oscilloscope requires its time bases and triggering to be linked. The main trigger triggers the main
time base, and then you can use a delayed trigger to trigger a delayed time base. Many digital oscilloscopes have also been
designed using this traditional, but complex, paradigm.
This instrument uses a simpler paradigm that cleanly separates the concepts of triggering and time bases. You can still do
everything that you could with an analog oscilloscope and more. Now these features are easier to set up and use.
