Modell 3500
16 low noise, high-gain, full-featured extracellular amplifier channels, designed for amplifying microvolt-level input signals.
Low Noise: 1 µV p-p
Flexible: Touch Screen and Computer Control
Integrated: MATLAB, LabVIEW Drivers
The Model 3500 features 16 independent channels, or amplifiers, a front panel touch screen, computer control capabilities and a built-in calibrator.
Users can also easily monitor the activity on any two channels via the convenient front panel BNC signal monitors.
Multiple instruments and multiple channels can be controlled from a single computer program.

- TTL Control of instrument mode
- Twin stimulation busses to pass current
- Channel Monitors
- Built-In Calibration signal
- Common Reference Bus
- Blanking
- PC control capability
- MATLAB® and LabVIEW SDK and drivers available
- 3U rackmount enclosure accommodates all 16 channels
Model 3500 Control Software
The Model 3500 is supplied with optional Windows control software. This software controls all features of the amplifier via a USB port (cable included).
The program also enables the storage of an unlimited number of 16-Channel parameter files, as well as provides a real-time notepad that logs changes in parameter settings or experimenter-added notations.
The Model 3500 includes:
- USB Cable: Type A to Type B
- 16 40-inch input cables
- Control software
- Operator's manual
- Rack mount hardware
- Power supply
