The OmniPlex System is a compact, flexible platform for high performance data acquisition and powerful online spike sorting. It offers low latency, superior common-mode rejection amplification and is well known for its user-friendliness. The OmniPlex System is a combination of the OmniPlex chassis, OmniPlex Software, and for new OmniPlex systems purchased today, a Digital Headstage Processor (DHP) subsystem – all described below. Other versions of the OmniPlex system could utilize an OmniAmp or DigiAmp A/D device.
- The compact OmniPlex chassis houses cards for synchronization and timing between system components, acquisition subsystem links, digital inputs for 64 channels and 32 auxiliary analog inputs for non-neural experiment signals.
- The OmniPlex System Controller operates the OmniPlex Software consisting of OmniPlex Server, the “software engine” for neural signal processing, and PlexControl, which is the main user interface providing data visualization and the user interface for interacting with the system.
- The Digital Headstage Processor (DHP) for use with digital headstages is Plexon’s most advanced subsystem. The DHP now enables up to 512 channels of neural recording, decreased sensitivity to ambient electrical noise, and lighter headstage cables with fewer wires for greater freedom of animal movement. Further, it offers real-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.
