UnEmap: 448 Channel Mapping

About

Research Application:  With a 448 channel base unit, UnEmap delivers unique high spatial resolution electrical mapping. The system is endlessly expandable to accommodate any desired number of electrodes, and is the only technology to enable recording from, or pacing down, electrodes individually.  Specific applications include:  •    Laboratory electrical mapping from small mice to large pigs •    High density mapping of atrial fibrillation •    Whole epicardial mapping •    Simultaneous epicardial and body surface potential mapping Integrated Package:    UnEmap is supported and delivered as a fully integrated package including electrode systems, data acquisition hardware and specialist software for managing signals on large data volumes. Designed for a diverse range of applications, many hardware parameters (e.g. gain, filters) are programmable.   Technical Specification:   SYSTEM  •    Maximum channels: unlimited •    Record from or pace down any electrode •    Isolate mode disconnects all electrodes from system •    Sampling rate 1 KHz to 5KHz •    Linux Operating System FOR EACH CHANNEL  •    Unipolar (common reference) •    Bipolar for differential signals •    Programmable – Gain 10 to 1000 – LP filter 50Hz to 5KHz – Stimulate or record – Stim. constant I or V •    High pass filter @ 0.05Hz •    Low pass filter 5th order linear phase •    Input impedance > 1TW • Input current < 5nA •    CMRR typical 90dB
