AC/DC Differential Amplifier
Suitable for EEG, ECG and extracellular recordings, it is ideal for teaching and is included in the Neuroscience Kit.
Overview
Used as a single-ended amplifier. It is designed for low-noise recording from excitable tissue and is suitable for EEG, ECG and extracellular recordings. It is ideal for teaching and is included in the Neuroscience Kit.
Included with the amplifier:
- A headstage for use with high impedance electrodes. The headstage supports record, stimulate and impedance modes.
Note: The AC/DC Differential Amplifier (AM3000H) with a headstage designed for use with glass pipette microelectrodes is also available. You will need to purchase Glass Microelectrode Holders separately.
Key Features
- 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.
