Model 3500 amplifier – A-M Systems
The A-M Systems Model 3500 amplifier is a low-noise 16-channel AC differential amplifier designed for amplifying microvolt signals detected via low-impedance electrodes (< 1.5 MΩ). It features a front panel touch screen, PC control, built-in calibrator, and front panel BNC monitoring of two channels.
Features of the Model 3500 Amplifier – A-M Systems
- 16 independent channels in a 3U enclosure
- Typical noise: 1 µV p-p (10 Hz-10 kHz)
- MATLAB & LabVIEW compatible touch screen and control via USB/PC
- 13 gain values from ×2 to ×20,000
- 8 high-pass filters (0.3 to 500 Hz) and 8 low-pass filters (100 Hz to 20 kHz)
- Notch filter attenuation > 35 dB at 50/60 Hz
- TTL control of instrument modes, dual stimulus busses
- Built-in calibrator, common reference bus, blanking and channel monitoring
- Supplied with 16 x 1 m input cables, BNC ports for each channel plus one common port, 3U rack kit, USB cable and external power supply
- 3-year warranty
