Post-Trigger or Delay-Trigger with Re-trigger
Use post-trigger or delay-trigger with re-trigger function when you want to
generate waveform after more than one trigger events. The re-trigger
function can be enabled or disabled by software setting. In figure 25, each
trigger signal will generate 2 single waveforms (since IC_Counter = 2), and
you can set
Retrig_no
to specify the number of the accepted re-trigger
signals. Note that a trigger would be ignored if it occurs during waveform
genera-
tion.
