Typical Evoked Potentials and EEG WorkstationsTDT Evoked Potential and EEG Workstations have been used to record an almost endless variety of bioelectric potentials including ABRs, VEPs, ERGs, EMGs, DPOAEs, and EEGs. Evoked potentials are transduced in our low impedance headstage, which features differential amplification, onboard impedance testing, and the low noise of an optically isolated, battery powered front end. Waveforms are digitized at 16-bit precision and sampling rates up to ~25 kHz, and transmitted to a DSP base station for further processing over a noiseless fiber optic link. Synchronized stimulus generation can be added by connecting additional device caddies in our modular zBus format. Systems are available with our powerful and time-tested turn-key BioSigRP software or the power and flexibility of our OpenEx software suite.

128 Channel EEG, EMG, and EP Workstation Ideal for EEG, EMG, intracortical, and high-count evoked potential recording, this system features 128 channels of data acquisition. The optically isolated preamplifier features fully differential amplification, and onboard impedance measurement. With our 18-bit analog-to-digital convertors, the system provides 100 dB of dynamic range and a 50 nanovolt noise floor. OpenEx software provides the experimental control and design interface for sophisticated experiments. Synchronized stimulus generation can be accomplished using onboard analog output or by adding high quality stimuluation modules from our System 3 line.

EEG, EMG, and Evoked Potentials Workstation Ideal for EEG, EMG, and high-count evoked potential recording, this system offers two channels of 24-bit D/A for stimulus generation and 16 channels of 16-bit A/D for data acquisition. The system can easily be expanded for higher channel counts. OpenEx, a customizable software suite for experimental design and control confers maximum flexibility. With its powerful data server that stores, indexes, time stamps, and serves up data quickly, OpenEx easily handles data storage, transfer, and visualization for large or high-count data sets. |

Auditory Evoked Potentials Workstation Combined with our powerful low-noise hardware platform, a pair of flexible turn-key software packages, SigGenRP and BioSigRP, give you complete control over your ABR recording setup. SigGenRP provides complete control over the stimulus waveform, level, timing, and calibration and provides a means for systematically varying stimulus parameters from one interval to another. BioSigRP includes full signal averaging and analysis capabilities including waveform display, comparison, and measurement in the time or frequency domain, filtering, waveform math (such as: add, subtract, or average selected waveforms), aligning or shifting waveforms in time, and automatic peak finding. Both are easy to use, with the power and flexibility needed for basic research applications. Adding Transducers TDT’s System 3 is a modular system that can be customized for a given application by selecting the necessary components from over 20 signal processing and conditioning devices. The above systems can easily be expanded to include a headphone buffer and transducers for complete stimulus production. A microphone amplifier and microphone can be added for DPOAEs or add a FlashLamp for visual stimulus and VEP and ERG recordings. Contact us to discuss a configuration for your lab.
