Model 15LT Bipolar
Specifications

APPLICATIONS

In combination with a high-performance notebook or desktop computer system, digitizing hardware, and specialized Grass recording and analysis software, such as Grass PolyVIEW® 16 or Gamma®, the Model 15LT forms the foundation for complete, high-performance digital recording and analysis systems for many biomedical research applications.

COMPUTER INTERFACE:
No More Knobs — Just Point & Click

All amplifier and calibrator functions are completely controllable via a standard RS-232 port from almost any computer system.

Windows® Program Simplifies Setup
Included with the system is a simple Windows program for setting and saving amplifier parameters and controlling system functions.

8- or 16-channel Amplifying System
Three Amplifiers with bipolar inputs are available:
15A54 Quad AC Amplifier
15A94 Quad EEG/PSG AC Amplifier
15A12 Dual DC/AC Amplifier
Select any combination of isolated amplifier models for up to sixteen total channels.

Minimum System Requirements for Link15:
Pentium 3, 800 MHz processor or better
128 MByte RAM
20 GByte hard drive with at least 3 MByte of free disk space
Windows 95/98/NT4.0/2000, WindowsXP operating system
1 free serial port (either Com1 or Com2)*
  *Note: A USB-to-serial port converter can be used for systems that do not have a serial port
