Introduction
SURPASS II is an advanced system for quantitative electromyography, nerve conduction studies and evoked potential diagnostics. Developed from over 30 years of neurophysiology experience, it combines modern hardware and multimodal software to support a wide range of clinical protocols. The QSA averaging technique can reduce recording time by up to 60%. The fully programmable Multimodality Stimulator allows combined stimuli for AEP, SEP, VEP and ERP workflows. The digital amplifier provides high‑quality, high‑speed recordings and can be expanded to 24 channels. USB 2.0 connectivity minimizes analog noise and the integrated 8‑bit trigger I/O supports complex stimulation setups. Both desktop and portable units run on Microsoft Windows with an MS Access patient database and a flexible report generator. A color‑coded control panel and intuitive display options improve daily examination workflow.
