This application note describes the procedure to determine a relational curve between specified latencies and the Inter-Stimulus Interval (ISI) using the online averaging feature in AcqKnowledge.
The Inter-Stimulus Interval (ISI) is the interval between stimulus pulses as generated by the STM100C module under software commands from AcqKnowledge. For averaging mode, this stimulus signal triggers a stimulus response that is read in by an MP unit many times for the purposes of reducing noise and smoothing the response. The repetition interval of the stimulus signal (ISI) is a critical factor for some averaging measurements, especially when a subject under test, who may be prone to unpredictable movement, necessitates rapid stimulus/response measurements. For large intervals, the latency factor dominates and as that factor decreases, other processing times become increasingly dominant.
