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 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

This 9-pin connector receives the signal from the

INPUT:

Headstage Probe for further processing.
