BIOPAC announces a Programmable Stimulation System for E-Prime to control stimulus frequency and stimulus intensity for real-time stimulus delivery changes based on a subject's responses. The system includes a Constant Current and Constant Voltage Linear Isolated Stimulator (STMISOL), USB 4-ch D/A Unit, software utility for communication between E-Prime and the stimulator, a sample E-Prime experiment with the necessary interface commands to communicate with the D/A unit, and interface cables. The D/A unit provides the stimulator with the appropriate voltage levels to stimulate a subject. The system supports up to four STMISOL and includes one.
