■ Trace Delay

The trace data which is acquired after one event occurrence is called a trace delay. There are two types of
trace delay depending on the event hit.
When the trace end trigger (event) hit occurs, the delay can be set within the scope of the block size (128 to
1024 frames). A block is sampled data in combination with the trace data before the event hit and the trace
delay.
When the multi trace end trigger (event) hit occurs, the delay is acquired as many as the number of
occurrence of the subsequent trace end trigger hit.
Example: If you want to get the trace delay for three blocks, the event hit needs to occur four times.
