eLab Data Acquisition System

  

hero title

 

eLab is a General purpose data acquisition system for recording action potential (Spikes), Field Potential, EEG, ERP, ECG and  EMG signals, and signal modulation by external digital events.
eLab is usable for Rat, Monkey and other Primates electrophysiology  recording
eLab  is combination of several  devices in one package.
They  are  microelectrode amplifier, stimulator isolator, pulse generator, digital and analog scope, amplitude window discriminator ,delay line, data acquisition and  powerful online spike sorting for spike clustering, built in digital micro drive.
Design of Microelectrode amplifier is optimized for low noise, high dynamic range, and low power dissipation. The novel aspect the amplifier is its ability to record EEG, LFP and single-unit signals simultaneously from the stream of one electrode by one ADC channel with 24 bit precision.

You can  Design The best possible  stimulus protocol  by a digital pulse generator. (single protocol or multi protocol )
eModule has two channel DAC(digital to analog converters) and to channel mechanical stimulator.
