| SynAmps2 |
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 don’t
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, we’ve 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 you’ve 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. |
