The following example shows the relationship of
TrigDe-
layCntStart
,
TrigDelayCntStop
, and
points
for
EXT trigger mode:
Figure 107 Measuring Multiple Intervals
In the above example,
TrigDelayCntStart(1)
and
TrigDelayCntStop(2)
specify one cycle of the wave-
form to measure the non-averaged period after each
trigger. That is, the number of triggers must be more than
or equal to points.
