RZ5D Base Processor

The RZ5 platform features two or three ultra fast digital signal processors networked on a novel bus architecture that speeds both onboard communication and memory access. It combines the power of user programmable digital signal processing and an optimized communications interface with support for Z-Series amplifiers, digital headstages, video trackers, and our Subject Interface. With the option to expand to up to four DSPs in either configuration, harness the power of a high-performance recording system at an affordable price point.

With a sampling rate of up to ~50 kHz, record high-frequency signals from your PZ amplifier. PCM analog outputs support a wide variety of signal production tasks, including control of motors and monitoring analog signals during acquisition.

Software control is implemented with circuit files developed using TDT’s RP Visual Design Studio RPvdsEx. Circuits are loaded to the processor through TDT run-time applications such as Synapse or custom applications via ActiveX controls.

The RZ5D standard configuration includes one standard DSP and two specialized DSPs, which can be used to analyze and store acquired data or to generate stimuli. Fiber optic input and output ports ensure low noise, optical isolation, and flexible system configuration.
