Advanced software features perform a full range of analysis
Easily acquire and analyze evoked response data
Perform a wide variety of evoked response studies with the powerful on- and off-line averaging features in AcqKnowledge®. Record and measure evoked potentials, Evoked Muscle Action Potentials (EMAP), late potentials, startle, nerve conduction and field potentials as well as visual, somatosensory and auditory evoked responses (P50, N100, P200, N200, P300, N300, N400, P600).
Ensemble averaging and epoch analysis features simplify Advanced Averaging and MP systems allow for Dual Stimulation. Averaging features make it possible to detect signals below the level of ambient noise. Use the stimulator functionality in AcqKnowledge® to output pre-defined waveforms, tones, tone pips, clicks (pulses) or other more complex waveforms. Calculate nerve conduction velocity and recovery time; investigate properties of muscle action potentials and fast nerve impulses. Record and analyze extra-cellular spikes.

Powerful Signal Averaging
Average physiological evoked responses in synchronization with stimulus presentation. Remove background noise and extract the signal of interest with the on-line signal-averaging mode. Use the Preferences to set the sweep duration and the number of averaging trials. Specify artifact rejection criteria, and determine the triggering options. Calculate the average and display the result in real time. Count and display the total number of averages, the number of averages left to complete the sequence, and the number rejected from the test. Display and overlap multiple responses for a quick comparison between subjects and trials.
Use averaging functionality to examine: Auditory Brainstem Response (ABR), Visual Evoked Response (VER), Auditory Evoked Response (AER) Sequence, Somatosensory Evoked Response, and Electrical Stimulation.
