GENERAL DESCRIPTION

The EMG-USB2 is a multichannel amplifier for bioelectrical signals. It can detect surface
electromyographic (sEMG) signals, intramuscular electromyographic (iEMG) signals,
electroencephalographic (EEG) signals and electrocardiographic (ECG) signals.
The EMG-USB2 allows the detection and recording of the electric signals generated by human
body. The signals acquired by the instrument are amplified, filtered, digitally converted and then
transferred to a PC, via an USB interface, for real-time visualization and storage. A freeware
software called OT BioLab has been designed by OT Bioelettronica and is available for download
on the website www.otbioelettronica.it, under the download page.
The EMG-USB2 is a research instrument designed for clinical research carried out by qualified
researchers. EMG-USB2 has been developed by the cooperation between OT Bioelettronica and
EMG & MOTOR UNIT LABORATORY of Aalborg University.
The EMG-USB2 is a modular system. It can amplify from 16 up to 256 bioelectrical channels, in
modules of 16 channels per board installed. The number of amplifier boards installed in the system
determines the total number of channels.
Several configurations of electrodes are possible by means of a number of cable adapters that
allow splitting the 7 amplifier inputs (16 channels for inputs: IN1, IN2, IN3 and IN4; 64 channels
for inputs: MULTIPLE IN1, MULTIPLEIN2 and MULTIPLE IN3).
EMG-USB2 allow to acquire, in any configuration, 16 additional signals on the auxiliary inputs
(AUX-IN). The signals can be generated by others amplifiers (e.g. force, torque, angle, position or
trigger signals) that do not need an optical insulation.
Custom amplification boards can be realized on user request to allow acquisition of other biological
and non-biological signals (MMG, force, etc.).
The EMG-USB2 instrument is completely safe for the patient. The safety is achieved by means of
medical grade electrical insulation of all the circuitry connected to the patient.
This user manual refers to all hardware versions of the instrument.
