Description

The Model 1800 Microelectrode AC Amplifier is a two-channel, differential amplifier intended for extracellular recording and/or stimulating with high impedance metal microelectrodes in research and teaching applications. Ideal for single-cell spike recordings, it can also 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.

Each channel of the Model 1800 contains a high-gain, low-noise differential amplifier stage followed by low-pass, high-pass, 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, x1,000, 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.
