Model 1600 amplifier – A-M Systems
The Neuroprobe Model 1600 amplifier from A-M Systems is designed for high-impedance intracellular recordings.
Description of the Neuroprobe Amplifier A-M Systems Model 1600
Amplifies, filters and injects current via a single electrode, with total control and digital display of membrane potential or injected current. Mains or battery powered, it is ideal for environments sensitive to electrical noise.
Features of the Neuroprobe Amplifier A-M Systems Model 1600
- Low noise: 13 µV RMS (10 Hz-50 kHz)
- Two levels of gain and current injection
- 10-turn potentiometers for fine adjustment (DC offset, balance, injection, capacitance)
- Selectable digital display (Digital Panel Meter): voltage, current or resistance
- Injection resolution: 0.1 nA
- Mains or battery powered (~10 h autonomy)
- Compatible with Model 6820 iontophoresis adapter (±200 V)
