Specifications
Temporal Specifica- Steady State Stimulus
tions Of Stimulus Initial Delay (elapsed time from present bar activation to 10% stimulus
Presentation amplitude): < 100 msec
Terminal Delay (elapsed time from present bar deactivation to 90% stimulus
amplitude): <100 msec
Rise time: 7.5 ± 2.5 msec
Fall time:
7.5 ± 2.5 msec
NOTE
Initial and terminal delays do not effect temporal measurement of ARLT
test (software compensates for them).
Multiplexed Stimulus (Used in Reflex Threshold test mode)
Period data for frequencies: 250 and 500 Hz:
Period 124 msec
Stimulus on time 44 msec
Stimulus off time 62 msec
Rise and fall time 18 msec
Period data for all other frequencies:
Period 115 msec
Stimulus on time 44 msec
Stimulus off time 53 msec
Rise and fall time 18 msec
Temporal Spec. Accuracy: ±10% or 5 msec, whichever is greater
