| NuAmps |
| 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 software and includes a 12-bit
trigger input port for synchronizing with external stimulators
such as the Neuroscan Labs STIM system for EP and ERP
measurements. Since NuAmps interfaces via USB, it is simple to
install and configure and requires no separate power supply. |
