Flexible trigger
options
A trigger may be set to
occur on a rising edge, falling edge, or change of state on any channel. It
may also be set for a level (pattern) condition by specifying a "1",
"0" or "X" (don't care) condition on all channels. Combinations
such as Edge OR Pattern, Edge AND Pattern, Edge THEN Pattern, Pattern THEN Edge,
etc, may be set. A pattern duration may be specified. Triggering may then be
set to occur should the pattern be shorter (glitch capture) or longer than the
set duration.
During unconditionally continuous
capture the screen updates at regular intervals. Continuous capture may be combined
with a trigger condition. In this case the screen will update only when the
condition is met. This is very useful for viewing continuously changing data,
which cannot be viewed with simple regular screen updates: e.g. data on a serial
line. By setting a condition you can view continuous screen updates, with the
data nicely placed in the middle of the screen, where you can watch the data
bits flipping. |
