The Model 3000 High-Gain AC/DC Differential Amplifier is designed for low-noise recordings from excitable tissue
Specific applications include EEG, EKG, extracelluar recordings, and more
This single-channel amplifier is packed full of features to accommodate your specific instrumentation requirements, yet fits into a compact enclosure for convenient placement in the lab. The standard input consists of a twisted-pair cable with an active shield. The ends of the cable are left bare to be wired to your input device
As an option, a headstage can be used to pre-amplify the input signal for high impedance glass or metal microelectrodes
The input mode can be set for either differential or single-ended recordings
External stimulus generators (such as the
Model 2100) can be easily used with the Model 3000 via the stimulus input. The stimulus mode allows the current passing through the electrode to be measured during stimulation at gain levels from 5 mV/µA to 1 V/µA. Both stimulus and recording modes can be controlled through an external gate signal, allowing for computer controlled switching
The Model 3000 provides a complete set of precision controls, allowing maximum control over stimulus and recording operations. The input can be amplified from 50 to 10,000 times in both DC and AC modes. A high resolution DC Offset adjustment is available up to ±250 mV, using Fine and Coarse adjustment controls. High Pass, Low Pass, and Notch Filters offer wide frequency selectivity
The small size of the amplifier and remote power supply offers the advantage of placing the amplifier next to the experimental set up, or within a Faraday cage with minimal power-line interference
