E signal This is a real world example captured from a real embedded system Down Sampled View Zoom 4 Another approach to making the table view useful in normal timing modes is to use down sampling This mode presents the data in a time linear format but down samples the data to reduce information Down sampling preserves linearity but reduces resolution This is similar to turning down the sample rate while capturing data to extend capture times at the expense of resolution Of course the key difference is we are post processing the data for the table view not ignoring data during capture In this mode we are simply displaying the data with less resolution to allow the user to see more transitions while maintaining a linear time view Since we have not changed the underlying data itself you can zoom in reduce down sampling at any time to see more detail and actual timing You can also link to other full resolution tables or waveforms to get a simultaneous view of 2014 TechTools 86 DigiView User s Guide the full detail and the data s correlation to other signals Delta vs Linear time Regardless of the display mode normal compressed or down sampled you can display the time field in absolute or delta time Absolute is the actual timestamp of the sample relative to trigger DELTA mode shows the time between table lines This is most useful in compressed mode where it tells you the time between transitions I
