General Description
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 accommodate 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.
Controls and Connectors
INPUT:
This 9-pin connector receives the signal from the
Headstage Probe for further processing.
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.
