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 x2 to x20,000
  • 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.

Model 3500 amplifier settings can be set either by the touch screen or by a Windows program.

The CHANNEL EDIT SCREEN is used to edit the parameters of the amplifier channels. The top line of all screens is the TOOLBAR with navigation icons.

Single Channel Parameters

The horizontal SINGLE CHANNEL SELECT LIST selects the channel whose current settings are displayed in the vertical parameter lists (High Pass, Low Pass, Gain, Notch, Reference, and Mode).

Pressing any value displayed in any list will highlight that value, and will immediately set that channel's parameter to the selected value. This is the equivalent of turning a dial or a knob on traditional amplifiers.

Transfer Channel Parameters

Parameters of a selected channel can be transferred by selecting the channel numbers from the double rows of the MULTICHANNEL SELECT LIST at the bottom of the EDIT SCREEN. Pressing COPY transfers the channel parameters to the selected channels.

16-Channel View

Pressing 16 at the top of any screen will display the 16-CHANNEL VIEW screen. The first 16-Channel view displays the most commonly changed parameters (High Pass Filter, Low Pass Filter, and Gain settings) of all 16 channels. Pressing the arrow in the lower right will switch the display to the other parameters (Notch, Common Reference, and Mode).

MAIN MENU Options

PROGRAM
