OmniPlex® Neural Data Acquisition System 30 years of experience and innovation with thousands of labs comes together in the OmniPlex® Neural Data Acquisition System, Plexon’s flagship electrophysiology research system. This system combines front-end amplification and acquisition with intuitive and powerful control and visualization software. The OmniPlex System incorporating Plexon’s Digital Headstage Processor (DHP) subsystem and digital headstages offers: Up to 512 neural recording channels R eal-time upsampling to 40kHz and adjustment of multiplexer timing offsets (equivalent to simultaneous sampling) for improved sorting quality, trodal acquisition, and software referencing – unlike other digital headstage based systems, U p to 250kHz per channel digitizing rate for high-frequency, non-neural experimental data such as audio signals, Decreased sensitivity to ambient electrical noise and lighter headstages With the DHP subsystem, researchers now have access to Plexon quality at very high channel counts with more affordable prices.
