SIU-V CONSTANT VOLTAGE
STIMULUS ISOLATION UNIT |
SIU-V Constant
Voltage Stimulus Isolation Unit
| Designed
to be used between the Grass S88X Stimulator and stimulating
electrodes to minimize artifact and provide greater safety
for stimulation. The SIU-V contains a radio frequency (RF)
oscillator which is modulated by the Stimulator output.
