22. persistence 313 How AutoScale Works 316 ait Agilent Technologies 257 6 Displaying Data Pan and Zoom 258 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 Some digital oscilloscopes go one step further by including the ability to further examine the signal details after acquiring them by panning and zooming through the waveform There is no limit imposed on the zoom ratio between the sweep speed used to acquire the data and the sweep speed used to view the data There is however a useful limit This useful limit is somewhat a function of the signal you are analyzing In normal display mode with vectors connect the dots off you can zoom in to the point where there are no samples on the screen Obviously this is far beyond the useful limit Likewise with vectors on you can see the linear interpolation between the points but again this is of
