Pan and Zoom
The ability to pan (move horizontally) and zoom (expand or
compress horizontally) an acquired waveform is important
because of the additional insight it can reveal about the
captured waveform. This additional insight is often gained from
seeing the waveform at different levels of abstraction. You may
want to view both the big picture and the specific little picture
details.
The ability to examine waveform detail after the waveform has
been acquired is a benefit generally associated with digital
oscilloscopes. Often this is simply the ability to freeze the
display for the purpose of measuring with cursors or printing
the screen.
To zoom an acquired waveform
1
Click on the Stop button to stop the signal acquisition.
2
Go to Analog panel by clicking the Analog button on the
toolbar or press Ctrl + 1.
3
On the Horizontal panel, click on
to zoom in or
to zoom out. You may also use the drop- down list to select
the zoom value. The following sample screen shots indicates
the waveforms after zoom in and zoom out.
