Neuroscan Compumedics Brasil |
Using the past two decades of experience and best
available technology, Neuroscan is pleased to offer the
SynAmps2 to the Neuroscience
community. Dedicated to high-density recordings,
SynAmps2 is a 70 Channel amplifier system,
consisting of 64 monopolar, 4 bipolar and 2 high-level channels. Each
channel has a dedicated 24 bit A-to-D, to ensure the most accurate
sampling available.
Active Noise Cancellation is an integral
feature of the SynAmps2
design, providing unparalleled noise immunity. This ensures an accurate
representation of the neurophysiological activity even in the most
hostile electromagnetic environments.
Using the latest technology has not only allowed us to make the
SynAmps2 our most capable
amplifier ever, it has also allowed us to put it into a small, cost
effective package.
SynAmps2 Consists of Three
Components:
Headbox Each Headbox consists of 70 channels, and multiple
Headboxes can be linked together to build high-density systems. Our
modular approach to amplifiers provides a simple and flexible upgrade
path.
All of the essential electronics have been moved to the Headbox. Our low
noise 24 bit A-to-D chip allows for low gain to be used while still
maintaining the resolution required for the most critical researcher.
Data is digitized immediately in the headbox and transmitted to the host
computer via a high-speed USB-2 connection guaranteeing lossless
transmission. Quality of the signal is assured by our impedance testing
circuitry, which allows you to verify impedance both on the Headbox and
in a software display.
Touch-proof connectors are provided to allow for the greatest
flexibility, while our high-density connector permits Quik-CapTM
to be easily connected. Inputs for high-level signals are also provided,
allowing you to capture the time series data of other measures along
with the EEG.
System Unit - Serving as a hub for multiple Headboxes, the system
unit is the distribution center, assuring absolute synchronization of
sampling and triggers between all of the Headboxes. The System Unit is
also the communication center with the host computer. Using a USB2
connection, the system unit ensures accurate transmission of data and
trigger timing information.
Power Unit Isolation of the subject from the power mains is a
critical safety aspect of a complete system. The Power Unit houses a
medical grade transformer, allowing you to connect those devices that
contact the subject to one reference point. This assures that leakage
currents and proper grounding meet world wide certification safety
requirements for patient connected devices.

Highlights.........................
Design Features
Headbox-Based Amplification - Analog signals, whether buffered
or not, are susceptible to noise. With the SynAmps2,
signals are amplified and digitized right at the patient side, providing
a digital signal transmission path and providing the very best signal
integrity.
70 Channel Headbox Units Allows you to use ALL of your
channels. The SynAmps2
offers two external auxiliary and four bipolar inputs in addition to the
standard 64 channels per headbox. You dont have to convert bipolar
channels to monopolar to get your full montage.
Check Electrode Impedances Right at the Headbox Electrode
impedances are checked against a user-selectable threshold and the
results are instantly available at the headbox.
Compact System Design Each system consists of one or more
headboxes, weighing in at less than 5 lbs, a system unit and a power
unit. System and power units will handle multiple headboxes for
high-density recordings.
Up to 256 EEG Channels on a Single Small System Unit - A single
system unit will handle up to four head boxes, creating a 256 channel
system in about one quarter the space of the original SynAmps unit.
Combine two system units to create a super-high density system.
Standard Windows Computer and USB 2.0 Interface Plug and play
operation makes connection and setup easy and fast. No proprietary
analog to digital, PCI or data interface cards need to be installed,
complicating the system. The industry standard USB 2.0 interface will
allow you to move to another PC easily.
Quik-Caps from Neuromedical Supplies Connect Directly -
Conversion (EBA) cables are no longer required for cap connection.
Neuromedical Supplies Quik-Caps connect directly to the quick-disconnect
high-density connector on each headbox for no-problem patient setup.
Touch Proof connections for each channel are also provided.
Technical Features
24-Bit Data Conversion Even within all the excellent high-bit
count analog to digital (A/D) converters currently on the market, weve
specially selected the quietest product available for use in the new
SynAmps2, delivering the best
signals with the greatest dynamic range possible. You demand clean,
high-resolution data and we deliver it. Data from the
SynAmps2 also flows seamlessly
through to the new 32-bit version of Scan.
Active Noise Cancellation Provides unparallel noise immunity.
This ensures an accurate representation of the neurophysiological
activity even in the most hostile electromagnetic environments
10G Ohm Input Impedance The very best in instrumentation
amplifier technology is used to ensure that your signals are faithfully
recorded.
External (auxiliary) Sensors can be Connected With Ease - Two
external inputs per headbox come standard. Both are isolated from
patient and computer connections with a+/-5 volt input range. Data is
time locked with the EEG data.
External (auxiliary) Sensors Require No External Power - Sensors
can be powered from the headbox. up to +/-10V at 100mA. This enables use
of strain gauges and a wide range of input devices where the output is
time locked to the acquired data.
Bandwidth/Acquisition Rates for the Studies You Want to Run
You want the capability to go from GSR to ABR in one instrument. If you
need extra bandwidth and higher acquisition rates,
SynAmps2 should be your device
of choice. With SynAmps2,
you will never wonder if part of the signal you needed for source or
other analysis is above the bandwidth of your data collection device.
Advanced Impedance Technology - Enables the use of advanced
impedance modeling techniques and allows you to obtain impedance of the
reference electrode in addition to the typical recording channels.
System Integration Features
Built-In Compatibility With Other Neuroscan Products - The
seamless system integration that youve come to expect from Neuroscan
continues with SynAmps2. A
totally integrated system including amplifier, data acquisition,
stimulus generation, data analysis, and source analysis means that you
spend your time doing research, not putting systems together.
Backwards Compatibility With Your Existing STIM or Other Stimulus
Generation Programs - SynAmps2
uses the same trigger connector that the original SynAmps and NuAmps
use, so there is no need to modify your existing stimulus protocols.
MagLink Compatibility SynAmps2
was designed with the difficulties of recording in the MRI in mind.
Specific engineering considerations were built in to the system to
provide the best possible recordings in the MRI.
Advanced De-blocking Circuitry - Allows for recording of TMS and
other high intensity stimuli, maximizing the data integrity without
affecting the amplifier.
Extended Cabling Systems Allows your headbox to be positioned
up to 10m away from the system unit for maximum flexibility. Cabling and
filters for shielded room patch panels will also be available.
Head box Mounting Options Multiple mounting options, including
wall, tripod and table mount, ensure that head box can be secured in
your recording environment.
Integrated Power Supply In addition to powering the
SynAmps2, the power unit will
allow you to power up to 4 additional devices, ensuring a common ground
is used in all of your patient connected equipment. |
