Higher channel count test example
This example shows how the Pulse Timing Preview is useful for higher channel count tests. The next
figure shows a four-channel test, reflecting the operation mode and voltages given in the next table.
When the channel count is higher, using the zoom feature provides a more detailed view of the
individual channel.
Expanded View zoom
On the Expanded View graph, drag the cursor to define the area to magnify (the cursor changes to a
magnifying glass). Note that each channel has a unique color and line width. When the channels
overlap, narrower lines are shown on top of the wider lines. To return to normal magnification, double-
click the graph or select Refresh. Multiple levels of zoom are supported, with a double-click returning
each level. Note that the Refresh option restores normal magnification (shows the Entire Test
waveform).
