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.

The Model 3500 offers:

• 13 gain settings from ×2 to ×20,000
• 8 high-pass filter settings from 0.3 Hz to 500 Hz
• 8 low-pass filter settings from 100 Hz to 20.0 kHz
• 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
