| Scan NuAmps
Express Neuroscan Compumedics |
Base Configuration Description:
The SCAN NuAmps Express is a fully functional research grade 40 channel
digital EEG and ERP recording system, which utilizes the full power and
capabilities of SCAN. This system will allow you to record EEG and
conduct spectral analysis, coherence and topographic mapping. Evoked
potentials (EP) and event related potentials (ERP) can be recorded,
averaged and processed in real-time. Event related spectral analysis,
coherence and time frequency measures can be computed. Amplitude and
latency measures, peak detection and comparative statistics are provided.
Additionally, SCAN provides a full research grade data proceeding tool
to remove noise and artifacts or decompose complex signals. Please see
the SCAN Features and Transform list for the full capabilities of SCAN.
SCAN allows for automation of acquisition and data processing. Real time
scalp impedance measurement is included, ensuring fast and simple set up
times. All acquired data can be exported for subsequent analysis and a
direct import to MatLab is provided. |
| Specifications: |
- NuAmps : The NuAmps is a 40 channel monopolar digital amplifier,
which connects to the computer via USB. It was designed as a portable
system that obtains power from a laptop computer. Computers powered by
the AC wall power supply require the optional isolation transformer to
meet FDA patient safety guidelines for leakage current. The NuAmps is
designed to work with Sintered Electrodes which provide the highest
quality and most durable electrical interface.
- The NuAmps has 40 monopolar channels for recording, these can be
accessed via the high density cap connector or the individual Touch
Proof connectors on the face of the amplifier. The SCAN software is
capable of computing bipolar derivations and different referencing
schemes. Reference and ground channels are included in the count of
the 40 channels. In additional to EEG and ERP, other physiological
measure can be recorded such as ECG, EMG and EOG. NuAmps are a DC
amplifier with a maximum sampling rate of 1000 Hz.
- The NuAmps has an 8 bit stimulus and a 4 bit response input that
allows integration of the STIM2 system triggers for recording ERPs.
The NuAmps does not have the facility to support high level signals
from external devices. Only TTL inputs are supported.
- The NuAmps are a digital amplifier and does not need to be
calibrated; however, the optional Pocketrace signal generator can be
used to verify calibration.
-
- SCAN Software: The SCAN software included with the SCAN NuAmps
Express package is a fully functioning version of the SCAN software.
However, due to the dramatic price reduction of SCAN for this package,
the NuAmps must be connected during the operation of the software and
no software key is provided. The SCAN license has the same warranty
and upgrade policies as any other SCAN license. Other promotions and
pricing specials do not apply to the SCAN license packaged with the
Express system.

-
- STIM2 Software: The STIM2 Software Only is provided with this
package. STIM2 runs under the Windows XP Professional OS and its
timing and accuracy is subject to the limitations of the Windows
operating system. Neuroscan makes no claims as to the accuracy of
stimulus presentation, trigger timing and audio calibration of the
STIM2 Software Only system. For details about the capabilities of the
STIM2 software, please see the STIM2 section of our webpage.

Hardware/Computer Requirements
Cable/Electrode Connections:
The SCAN NuAmps Express system requires two computers to be fully
operational, one for SCAN and the NuAmps and the other for the STIM2
system. These computers are not included in the SCAN NuAmps
Express Package price, but may be purchased separately. In typical
configurations these computers will be laptops running under the Windows
XP Professional operating system. Minimum specifications for the
computers are Pentium 4 processors, 256 MB RAM, and 64 MB video RAM. The
computer must support USB and USB2 connections.
The connections to the equipment are as follows: The laptop running SCAN
connects to the NuAmps via a USB connection. The STIM2 computer connects
to the NuAmps via a DB25 pin connector and pigtail converter cable. All
of the above cables are included with the SCAN NuAmps Express Package.
If the computers are connected to the AC wall outlet, an isolation
transformer is required to meet the FDA requirements for leakage
current of patient connected devices.
The NuAmps amplifier is designed to record from Sintered Ag/AgCL
electrodes. Either individual or cap based electrode systems can be used.
Electrodes are sold separately. |
