RHD Controllers
Product Discontinued
The RHD USB interface board was discontinued in February 2022 due to supply chain issues. Please use the RHD recording controller instead.
The RHD recording system offers several options for a USB-linked controller: the 512-channel or 1024-channel RHD recording controller, and the 256-channel RHD USB interface board.
Each controller supports multiple RHD recording headstages, sampling each amplifier channel up to 30 kSamples/s. Each controller also has a number of digital and analog inputs that are sampled in synchrony with the headstages, allowing users to tie in other laboratory equipment to one data acquisition system.
The controllers have analog outputs that can reconstruct selected digitized amplifier signals back to analog waveforms in real time. Two of these analog signals are also routed to the left and right channels of an audio out line jack, which can be connected to an audio amplifier for real time monitoring of any two headstage signals.
Each controller has digital outputs; eight of which can serve as low-latency threshold comparators that operate on the signals routed to the analog outputs.
