XLTEK EEG32U Amplifier User and Service Manual
4
Introduction
The XLTEK EEG32U amplifier offers advanced signal acquisition capabilities for accurate data
acquisition with 1kHz sampling rates and 16 bit analog-to-digital data conversion. The highest signal-to-
noise ratios and fast recovery from saturation for stable baselines are available with the
EEG32U . This
rugged device was designed with extensive clinical input to meet the workflow and application needs of
the basic EEG Lab.
EEG32U features include:
•
USB connectivity to XLTEK Desktop or Laptop
•
32 referential channels
•
Patient-event switch interface
•
Photic-stimulator interface for EEG applications
WARNING: We strongly recommend that you read the Warnings and Cautions section of
this manual before operating this amplifier.
Product Intended Use
The EEG32U Amplifier is intended to be used as an electroencephalograph to acquire, display, store and
archive electrophysiological signals. The amplifier should be used in conjunction with Natus
NeuroWorks™ software to acquire scalp electroencephalographic (EEG) signals.
The EEG32U Amplifier is intended to be used by trained medical professionals, and is designed for use in
clinical environments such as hospital rooms and epilepsy monitoring units. It can be used with patients
of all ages, but is not designed for fetal use.
Essential Performance
Essential performances of the EEG32U amplifier are identified in the standard IEC 60601-2-26:2012.
Essential performance relates to the quality of the signal recorded from the amplifier. Specific essential
performances are:
(1) accuracy of signal reproduction
(2) dynamic range and differential offset voltage
(3) input noise level
(4) frequency response
(5) common mode rejection
The definition of these essential performances can be found in the standard.
