Intan RHD Recording System
The Intan RHD recording system is a modular, low-cost electrophysiology data acquisition system built around the Intan RHD family of microchips. The RHD recording system with USB interface and open-source software allows users to observe and record up to 1024 signals from multiple RHD headstages.
Hardware
You need three basic components for a RHD recording system
RHD recording headstage
These are small circuit boards containing an Intan RHD amplifier chip that amplify, filter, and digitize signals from 16, 32, 64, or 128 electrodes. Unlike traditional headstages that provide limited analog amplification, Intan headstages perform all amplification on the headstage and produce a digital data stream conveying the signals from all electrodes.
RHD recording controller
This acts as a digital hub that links one or more headstages to a computer via a standard USB port. The RHD recording controller supports up to 1024 amplifier channels in a rack-mountable case with robust digital and analog I/O ports. Additional I/O ports may be added by using the optional I/O expander.
SPI interface cable
These cables link the headstages to the recording controller or USB interface board, sending power to the headstage and data back to the controller. They come in 1-ft (0.3 meter), 3-ft (0.9 meter), and 6-ft (1.8 meter) lengths, and in two thicknesses: standard and ultra thin. Multiple cables can be daisy-chained to create longer cables.
Software
Intan provides free software to operate this system. The software allows users to select amplifier bandwidths and sampling rates, measure electrode impedances, view live signals from electrodes, and save data to disk. Recording sessions may be controlled manually or triggered automatically by external digital signals. We also provide free software to load saved data files into MATLAB, Python, or Julia, or to convert data files to NEX format.
We provide compiled, ready-to-run software for Windows PCs or Macs. You can download it and try it out before you buy Intan hardware; it will run in demo mode. We provide open-source C++/Qt source code that can be compiled for Linux.
Electrodes
Intan does not manufacture or sell electrodes, but many third-party companies sell electrodes that are compatible with our headstages. A list of compatible electrodes is provided with each RHD headstage.
Commutators
Many of our customers use our system with commutators (i.e., slip rings or swivels). We do not sell commutators, but we do provide an application note describing how to adapt our SPI interface cables to any basic commutator. Also, Intan-ready motorized commutators with optical fiber ports are available from Alpha Omega (AlphaComm-I) and Doric (commutator with Intan adapter). Since our interface cables use purely digital signals, operation with commutators is typically robust and free of movement-induced noise.
Wireless
Intan Technologies does not manufacture or sell any devices with wireless telemetry, but several third-party companies have developed wireless electrophysiology products and data loggers using Intan RHD amplifier chips.

RHS (Recording and Stimulating) Systems
The RHS stimulation/recording system with USB interface and open-source software allows users to stimulate and record up to 128 signals from multiple RHS headstages. The minimum required components for a functional RHS system are: a stim/recording controller, a Stim SPI interface cable, and an RHS headstage.
Hardware
You need three basic components to assemble a functional electrophysiology stim/recording system
RHS stim/recording headstage
These are small circuit boards containing an Intan RHS stim/amplifier chip that amplify, filter, and digitize signals from 16 or 32 electrodes and provide constant-current stimulation pulses. Unlike traditional headstages that provide limited analog amplification, Intan headstages perform all amplification on the headstage and produce a digital data stream conveying the signals from all electrodes.
RHS stim/recording controller
This acts as a digital hub that links one or more headstages to a computer via a standard USB port. The controller can stream up to 128 amplifier channels to a host computer at user-selectable sampling rates up to 30 kS/s per channel.
Stim SPI interface cable
These cables link the headstages to the stim/recording controller, sending power to the headstage and data back to the controller. They come in 3-ft (0.9 meter) and 6-ft (1.8 meter) lengths. Multiple cables can be daisy-chained to create longer cables.
Software
Intan provides free software to operate this system. The software allows users to select amplifier bandwidths and sampling rates, measure electrode impedances, view live signals from electrodes, and save data to disk. Stimulation parameters may be configured in the GUI; stimulation pulses are triggered by digital inputs or keypresses. Recording sessions may be controlled manually or triggered automatically by external digital signals. We also provide free software to load saved data files into MATLAB, Python, or Julia, or to convert data files to NEX format.
We provide compiled, ready-to-run software for Windows PCs or Macs. You can download it and try it out before you buy Intan hardware; it will run in demo mode. We provide open-source C++/Qt source code that can be compiled for Linux.

Warranty
We guarantee our products to be free of material defects for 90 days of normal use within specification. Because our products are used in conjunction with customer hardware, we have to assess each situation on a case-by-case basis. This warranty does not apply to products that have been modified in design or function, subjected to abuse, misuse, mishandling, or unauthorized repair. Within the 90-day use period, however, if the failure is found to be strictly from our product from normal use within specification of components on-board, we will repair or replace (at our option) the product if returned to us in its original condition. Contact us for return information prior to returning any products. We do not refund shipping costs.
