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.

ABR and DPOAE Workstation This system combines our powerful low-noise, high bandwidth hardware with our easy to use BioSigRZ software for ABR and DPOAE recordings. Targeted for single-channel animal screening protocols, the system includes two channels of 24-bit Sigma-Delta DACs and supports a maximum sampling rate of 200 kHz. Support for a variety of transducers is built into both the hardware and the software. A comprehensive set of calibration and experiment configuration files are also provided with the system, minimizing experiment set-up and streamlining daily operation. BioSigRZ software 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.  |

32 Channel EEG, EMG, and EP Workstation Ideal for EEG, EMG, and evoked potential recording, this system features 32 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 stimulation modules from our System 3 line.
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 FlashLamp for visual stimulus and VEP and ERG recordings. Contact us to discuss a configuration for your lab. See our list of TDT transducers for Evoked Potentials and other manufacturer's products available from TDT.
