SynAmps RT |
|
| |
|
Usando as duas últimas décadas de experiência e a melhor tecnologia
disponível,
a
Neuroscan
tem o prazer de oferecer à comunidade neurocientífica o
SynAmps RT.
Dedicada às gravações de alta densidade,
em um sistema de amplificação de 70 canais, com 64 monopolares e 4
ou 2 canais de alto nível.
Cada canal têm um conversor AD de 24 bits, para garantir uma
amostragem mais precisa. |
|
| |
|
|
|
|
| |
|
|
|
|
| |
 |
|
Active Noise Cancellation is an integral feature of
the SynAmps RT 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
SynAmps RT our most capable amplifier ever, it has
also allowed us to put it into a small, cost effective package. |
|
| |
|
|
|
| |
|
SynAmps RT 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. |

SynAmps RT Highlights |
|
| |
|
|
|
| |
|
Design Features |
|
| |
|
|
|
| |
|
Headbox-Based Amplification - Analog signals,
whether buffered or not, are susceptible to noise. With the
SynAmps RT, 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 SynAmps RT
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 SynAmps RT,
delivering the best signals with the greatest dynamic range
possible. You demand clean, high-resolution data and we deliver it.
Data from the SynAmps RT 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 |
|
| |
|
|
|
| |
|
1 G 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,
SynAmps RT should be your device of choice. With
SynAmps RT, 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 SynAmps RT. 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 - SynAmps RT
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 - SynAmps RT
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 SynAmps RT, 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. |
