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

Software for Windows control is an optional feature of the Model 3500. Through a USB port (cable included), this program manages every aspect of the amplifier.

A real-time notepad that records modifications to parameter settings or annotations written by experimenters is provided by the application, which also allows for the storage of an infinite number of 16-Channel parameter files.
