 Multi-modal data acquisition system with active electrodes
ActiveTwo is a powerful new
high-resolution biosignal acquisition system that incorporates some revolutionary
concepts. Active
electrode technology is just one of the
significant innovations in the ActiveTwo system. By placing active
electronics within millimeters of the actual electrode contact,
ActiveTwo
virtually eliminates the need to prepare the scalp before applying electrodes.
This can cut measurement preparation time by an estimated 15 -30 minutes for
most laboratories!
ActiveTwo can also be equipped with additional sensors for respiration,
skin conductance, temperature, plethysmograph (pulse) and other
parameters. An optional isolated analog input box makes it
possible to acquire almost any type of signal synchronously with the
signals sampled by the ActiveTwo A/D box.
As an added benefit, ActiveTwo comes with powerful data
acquisition software developed in National Instruments' LabView. We
provide the compiled software so you do not need to own LabView, and you do not
need to be a programmer to operate the system. For those laboratories with
programming resources, the source code is provided so that you can add any
special features that you may need. |

New Features of
ActiveTwo
- Optional optically
isolated auxiliary signal input box for simultaneous acquisition from unisolated
signal sources or for acquisition from multiple patients at the same time.
- Synchronized 24-bit
sampling, no skew, zero-reference principle.
- Sigma-Delta converter
technology offers > 100 dB dynamic range, guaranteed no missing codes, and less
than 10 ppm integral non-linearity.
- Fully DC coupled operation
in all modes, +/-262 mV input range, no high-pass filtering in hardware.
- Adjustable sample rate: 2,
4, 8 or 16 kHz sample rate per channel (throughput is 1.5 MB per second).
- Up to 280 channels in an
integrated front-end.
- Synchronous acquisition from multiple subjects with perfect
electrical isolation on a single host computer.
Key Benefits
- Fast application time
without skin preparation.
- Reliable measurements
due to low-noise design.
- LabView
acquisition software comes with source code so you can implement changes as
you see fit.
- Low cost!
Cost-per-channel actually decreases as the number of channels increases.
- Number of channels can be upgraded easily, up to 280.
- Compact front-end is
battery powered for improved data quality.
- Only system on the
market with active electrodes.
- Only 24-bit biopotential
measurement system on the market with this collection of features.
- DC amplifier with the
largest input range. This
is the first DC amplifier with an input range like that we have come to
appreciate in typical AC designs. The ActiveTwo simply will not saturate
on difficult electrodes.
- Only system with 280
channels in an integrated design, no coupling of sections/boxes with its
inevitable increase of interference and reliability problems.
- Only battery-powered,
fiber-coupled system with more than 64 channels.
- Highest sustained data
throughput. 1.5 MB/s of raw data is processed by the PC. All this
data can be stored to file without any data-reduction if required.
- Only system with
completely open (LabVIEW) software environment.
