Featuring Model 15 Neurodata Amplifier System

Thirty-two channels of fully programmable amplifiers featuring a bandwidth of 0.01 Hz to 6 kHz, and selectable high and low pass filters housed in a compact 5.25" x 19" rackmountable bin, offer superb performance for multichannel EEG, EMG, ECG and multiple unit recordings. The Model 15A54 amplifier has amplification from 50 to 200,000, 5-position 4-pole active Bessel low pass filters, and a noise level of less than 6 microvolts peak-to-peak, referred to the input at the 6 kHz bandwidth. The high pass filter has eight positions from 0.01 to 100 Hz. A line frequency filter is also selectable. This system provides true 250 volt subject isolation.

A novel Windows® control program, Link15, is provided to facilitate amplifier control via a standard RS232 port on the PC. Link15 is embedded in Gamma®, an optional 36-channel data acquisition software package. This feature simplifies setting up montages by automatically setting amplifier parameters based on the signal type. A built-in calibrator with both AC and DC voltages, electrode impedance test circuit and trace restoration are additional features accessible from within Gamma.

Gamma is a state-of-the-art, 32-bit, Windows application developed expressly for the biomedical community for long-term physiological signal acquisition, review and measurement. It offers an extremely easy to use, highly interactive user interface that any researcher will find friendly. Add expanded analysis capabilities to include Spectral Trend View, FFT Spectral Analysis, Zoom/Filtering capabilities, and custom plug-in software modules.
