NuAmps is a high-quality and inexpensive 40-channel digital EEG amplifier that is capable of 22 bit sampling at 1000Hz, measuring signals from DC to 260Hz. It is fully compatible with the SCAN and Curry software and includes a 12-bit trigger input port for synchronizing with external stimulators such as the Stim2 system for ERP measurements. Since NuAmps interfaces via USB, it is simple to install and configure and requires no separate power supply. The ampli­fier is small size, but big in features includ­ing 40 chan­nels of DC EEG that is about the size and weight of a paper­back book (1.3 lbs.).
