RHS Stim/Recording Controller
The Intan RHS stim/recording controller (Part #M4200) allows users to record electrophysiology signals and perform electrical stimulation across 128 channels using small, affordable hardware and free, open-source software. This device connects to a host computer via a USB 2.0 cable. Small 16- or 32-channel RHS headstages connect to the stim/recording controller via thin, flexible all-digital Stim SPI cables.
- Supports all Intan RHS headstages with sampling rates of 20, 25, or 30 kS/s.
- All headstage channels can independently produce stimulation currents from ±10 nA to ±2.5 mA with ±9V compliance.
- Biphasic or triphasic stimulation pulses are generated with timing resolution as fine as 33 μs.
- Stimulation pulses are pre-configured in software and triggered by keypresses or digital inputs.
- Independent ground isolation on each headstage port to reduce noise from ground loops.
- Software supports in situ electrode impedance measurement.
- Two analog input ports and two analog output ports with ±10V range.
- Two digital input ports and two digital output ports.
- Analog and digital inputs are recorded in sync with amplifier waveforms; may be used to trigger stimulation pulses or to control automated episodic recording sessions.
- Optional I/O expander increases the number of auxiliary ports to 8 analog in, 8 analog out, 16 digital in, and 16 digital out.
- May be mounted in standard 19" rack (1U) or operated from a bench top.
Note: RHD recording-only headstages and SPI cables will not work with the RHS stim/recording controller. The RHS headstages require additional voltage and control signals that are not present in the RHD system.
