PLUGSYS Programmable Stimulator Module (PSM)
Constant current square wave stimulator for isolated tissue studies
The Programmable Stimulator Module (PSM) is a square-wave, single-channel stimulator with isolated constant-current (1 channel) output for the PLUGSYS system. It has been developed specially for stimulating isolated tissue in physiological and pharmacological research. It is ideally suited for computer-controlled tissue bath setups, e.g. for automatic refractory period determination.
This module is operated through software from a PC. Adjustments are made from the PC and transferred to the PSM through a control program.
Software Required (either)
73-3497 Programmable Stimulus Module for PSM and PPG Control
This module can control up to 8 PSM or PPG modules. For each module, basic rhythm, pulse width, output polarity and output current can be set individually. Train function is also selectable, train rhythm and train duration is applied to all modules.
73-0024 Data Acquisition Software Control Module for PSM and PPG
This module controls the PSM or PPG through ACAD, ISOHEART, NEURODYN Data Acquisition Software.
