TDT Series 3

Description

The TDT System 3 was introduced in the late 1990. It is a versatile and widely used data acquisition and processing system in the field of neurophysiology and electrophysiology research. It's a hardware and software platform designed for acquiring, processing, and analyzing neural signals.

Key features of the TDT System 3 include:

• High-Speed Data Acquisition: It is capable of recording neural signals, such as multi-channel electrophysiological data, at high sampling rates.
• Flexible Signal Processing: The system provides a range of signal processing capabilities, including filtering, spike sorting, and event detection.
• Integration with MATLAB: MATLAB compatibility is a notable feature, making it easier for researchers like yourself who use MATLAB for data analysis and programming.
• Customizable: Researchers can customize and expand the system with additional modules and accessories to suit their specific experimental needs.
• Multi-Channel Capability: It can handle multiple channels simultaneously, which is crucial for studying neural activity in various brain regions.

System 3 devices

RP2.1 Enhanced Real-Time Processor

The RP2.1 is a single core Digital Sound Processor. It can be programmed by the RPvdsEx programming interface. It can generate signals or play signals from memory as well as record signals.

• Sample rates: 6, 12, 25, 50, 100, 200 kHz.
• Analog I/O: 2 channels in, 2 channels out
• Digital I/O: 16 channels configurable

RA16 Medusa Base Station

The RA16 is a single core Digital Sound Processor that can be interfaced with a multichannel ADC preamplifier like the RA8GA or RA4PA.

• Analog Input: up to 8 channels with external preamp via optical link
• Analog output: stereo via 6.35mm jack
• Digital I/O: input 1 bit (trigger), output 16 bits
• Sampling rate: 48.828 kHz maximum

RA8GA Adjustable Gain Preamplifier

The RA8GA is a 8 channel ADC device with adjustable preamp. It must be connected to the optical link input of a medusa base station (RA16) or RZ6. The RA8GA has female Dsub25 connector for the analog inputs. It is meant to be used with the PP16 patch panel with BNC connectors.
