Electromyogram Amplifier
Evoked Response Amplifier
The EMG100C amplifies general and skeletal muscle electrical activity. The amplifier functions directly with AcqKnowledge to perform
real-time EMG integration and, as it incorporates fast response and
settling time characteristics, can also be used to monitor single-fiber
EMG, motor unit and peripheral nerve action potentials.
The ERS100C is an extremely low noise differential amplifier that
accurately amplifies very small potentials, such as those associated
with stimulus/response, signal-averaged recordings. Selectable gain
and bandwidth options make the module useful for a variety of
evoked response testing modes. The ERS100C is intended for use in
applications such as auditory brainstem response, startle response,
somatosensory evoked response or nerve conduction velocity
recording.

Electromyogram Amplifier
Electrooculogram Amplifier
The EOG100C amplifies the corneal-retinal potential. The amplifier
monitors the DC potential on the skin surrounding the eyes, which is
proportional to the degree of eye movement in any direction. The
amplifier output can be switched between normal EOG output and
Derivative of EOG. In Derivative mode, the amplifier outputs the
measured velocity of eye movement, which is useful for saccade and
nystagmus investigations. The amplifier permits DC coupling to electrodes for X/Y graphing of eye movement without discernible decay.

Biopotential 100C Interface Cables
The Biopotential amplifiers connect to
unshielded or shielded electrode leads terminating with Safelead®/Touchproof (1.5mm)
sockets. For best performance, use two shielded
electrode leads and one unshielded electrode
lead per amplifier. See the extensive selection of
electrode leads on page I135. For additional
electrode lead distance, see the Module
Extension Cables on page I139.
