MS4/MS16 Stimulus Isolator
MS4/MS16StimulusIsolator
MS4/MS16Overview
The MS4/MS16 Stimulus Isolator converts digital waveforms into analog current
waveforms as part of a computer controlled neural microstimulator system that delivers
user-defined current waveforms through multichannel electrodes.
TheMicroStimulatorSystem
A typical system consists of an RZ5 or RX7 processor base station (RX7 must be
housed in a zBus Device Caddie with power supply and interface module), an MS4
or MS16 Stimulus Isolator, ACC16 AC Coupler (Optional) and NC48 or HV250
Battery Pack.
The block diagram below illustrates the functionality of the system.
MultichannelMicroStimulatorSy s te mDiagram
As seen in the illustration above, stimulation control waveforms for each electrode
channel are first defined on the base station and digitally transmitted over a fiber
optic cable to the battery powered stimulus isolator. On the isolator, specialized
circuitry for each electrode channel generates an analog current waveform as specified
by the digital stimulation control waveform.
