9.7 TIME DATA DISPLAY (OSCILLOSCOPE)<br />
The time data (Fig. 9.7) is an ancillary display to an FFT or RTA executed measurement.<br />
Here we see a 100Hz sinusoid captured and analyzed with a 16K FFT.<br />
Figure 9.7<br />
The time data display has a number of particular features that allow, out of user<br />
control, for automatic scale adjustment and triggering of the displayed signal.<br />
The time information displayed is the processed data only. The user can zoom in and<br />
out of this data but it is not possible to display more than one acquisition area. Fig. 9.8<br />
shows this effect; the same 100Hz sinusoid as before seems now truncated; this means<br />
that we only reached the maximum displayable data, in case of a 16K FFT @ 51200Hz<br />
sampling this is exactly 320ms.<br />
