Multi-channel
EMG and Footswitch System
Easy to setup and use, the MA-300 is
available in three configurations. This innovative digital EMG system
has been designed for use in any Gait, Rehabilitation or Physical
Therapy laboratory. As in our other products, the MA-300 continues
to uphold our high standards of system integrity and reliability
to produce a fully calibrated EMG signal.
The MA-300 is available in six, ten and
sixteen channel versions. Each system provides detection of full
bandwidth EMG activity, (20 Hz - 2 k1U) and supports eight foot
contact switches. A thin, super flexible, 3/32" diameter coaxial
cable transfers information from the lightweight backpack (worn
by the subject) to a slim desktop receiver. The cable also supplies
isolated power to the backpack thus eliminating the need, and expense,
of batteries. The system is compatible with most major PC data collection,
commercial gait and motion analysis systems. Digital error-correcting
telemetry techniques are used to ensure that data is always accurate.
The top of the line system offers sixteen
channels, and also provides four additional "research"
channels. The frequency response on these additional channels, (DC
to 150 Hz), makes them suitable for EKG, goniometer, and pressure
sensors etc. Versatility is key with the MA-300. Whether you chose
the six channel, or the ten channel system, you have the option
to upgrade your system at any time.
MA-300 FEATURES
- Up to sixteen channels
of calibrated EMG using active EMG electrodes.
- Supports eight disposable foot
contact switches (supplied).
- Easy to use - all-digital
signal eliminates gain controls and guarantees calibration.
- Includes low pass filters
on all EMG channels (an extra on many systems).
- Reliable - requires no
user configuration or setup.
- Analog signal output
is compatible with gait and motion analysis systems.
- Supplied complete with
everything necessary to start recording EMG in the gait lab.
SUBJECT BACKPACK
- Contains digital data
transmission module plus electrode & foot switch connections.
- Includes an adjustable
digital anti-alias filter.
- Easily attached to our
jackets and belts worn by the subject.
- Transfers data to the
Desktop unit via 60 foot ultra-thin 3/32" diameter cable.
DESKTOP UNIT
- Decodes EMG and foot
switch data to produce standard analog signals.
- Complete digital signal
processing for low noise and no interference.
- Supplies isolated DC
power to the subject backpack.
