The Model 1700 Differential AC Amplifier is perfect for excitable tissue recordings, whether in a reseach laboratory or teaching environment.

Common applications include, but are not limited to:

Multiple-Unit Recordings

Evoked Potentials

EEG/EMG/EKG/ERG recordings

Long-term Potentiation

The Model 1700 Differential AC Amplifier contains 4 independent amplifier channels in a single enclosure enabling the researcher to record multiple signals simultaneously. Each channel contains a high-gain, low-noise differential stage followed by low-pass, high pass, and notch filters. A connection is also provided for a stimulator input so that recording or stimulating through the same electrode is possible without having to change cabling.

Standard gain settings are x100, x1000 or x10,000, but they can be modified to meet your specific requirements. High and Low Pass filters are 2nd order Butterworth filters, and like the gain, the standard settings can be modified to meet your needs if required.

The Model 1700 Differential AC Amplifier is designed for use with low impedance (<1.5 MΩ) electrodes, and is therefore suitable for use with suction, nerve cuff, hook, surface, and simple metal electrodes. Optional record only headstages are available for situations where you would like to record from electrodes with higher impedances such as those used when recording neural spike action potentials.
