General Description
Instrument Features
The
AC Microelectrode Amplifier Model 1800
is a two-channel, differential amplifier with
headstage probes. The instrument is intended
for extracellular recording and/or stimulating in
conjunction with high impedance metal
microelectrodes. It can be used in a number of
research or teaching applications requiring
extracellular neurophysiological recording from
excitable tissue, such as nerve, muscle (EMG), EEG,
EKG, and ERG recordings.
The instrument is not
intended for clinical measurements using
humans.
Each channel of the
Model 1800
contains a high-gain, low-noise differential amplifier
stage followed by low frequency, high-frequency, and notch filters. Three operating modes
are available to accomodate recording, stimulating, and verification of electrode
impedance. Record Mode offers three levels of signal gain (x100, x1000, x10 000).
Stimulus Mode allows the current passing through the electrode to be measured during
stimulation. Impedance Mode utilizes an internally calibrated current source to allow in
situ verification of electrode impedance.
