Example 2: Triggers in 2 Channels
a Trigger rising edge: Start of the recording of the pre-trigger time and the retrigger blocking time,
as well as with the 1st trigger event start of the maximum record time
b Trigger falling edge
c End of the retrigger blocking time, channel 1
d End of the retrigger blocking time, channel 2
e End of the post-trigger time
f End of the maximum record time
t Time line
When a trigger event occurs, the start trigger (a) trips a fault record. Another limit violation of the second
channel occurs within the retrigger blocking time of the first channel (c). This extends the fault record (e)
because the retrigger block acts only on the appropriate channel.
Each individual channel can trip a retrigger. The retrigger blocking time can be activated separately for each
analog input.
Retrigger Blocking Time with Trigger Reason
Each threshold (Max. trigger, Min. trigger, dM/dt rise (/Filter time) or dM/dt drop (/
Filter time)) of a channel has its own retrigger blocking time. That is, for example, one Min. trigger
can extend the recording started by the Max. trigger once (see the figure below).
