Time Scales
When setting the time scale for viewing and capturing a wave it is important to
choose the right setting. The chosen scale during live viewing sets the sample rate
and the saved wave length since the buffer is always 4096 samples long.
After a wave has been saved it can be zoomed in for more detail. Because a live
wave is compressed to five samples per LCD pixel, zooming in after it is saved will
show more actual detail than was observed in the live view.
Alternately, when viewing a live wave, the LCD only shows 1/4th of the data buffer
that will be in the captured wave. The extended viewing capability means that you
may want to zoom in more on a particular wave, even if part of the signal is not
visible, knowing that it will be in the saved wave. This also provides more detail in
the saved wave because of the faster sample rate.
