Pentusa BioAmp Base Station

RX5

RX5 Pentusa Base Station

The Pentusa’s fast clock speeds and distributed architecture deliver the processing power and transfer rates you need to process multi-channel neurophysiology data in real-time. This means you’ll get excellent performance in applications that require fast data transfer for real-time control and data visualization or for high volume data transfer tasks such as streaming data to disk. PCM analog outputs support a wide variety of signal production tasks, including control of motors, electrical stimulation, and monitoring analog signals during acquisition.

Used with the Medusa battery powered preamplifiers, the Pentusa is a biological amplifier system that provides simultaneous ~25 kHz acquisition on every channel, fiber optic isolation, and the power of user-programmable real-time DSPs. The system’s versatile design allows you to switch from extracellular recording to EEGs simply by changing headstages. Programming and control of as many as 32 single-unit channels or 64 EEG channels can be accomplished on a single device. For systems with up to 256 channels, consider our RZ2 base station and PZ2 preamplifiers.
