SIU5 RF TRANSFORMER ISOLATION UNIT |
|
Designed
to be used between a Grass Stimulator and the stimulating
electrodes to minimize artifact and provide greater safety
for stimulation. The SIU5 contains a radio frequency (RF)
oscillator which is modulated by the Stimulator output.

PSIU6 PHOTOELECTRIC ISOLATION UNIT |
|
The Model
PSIU6 is an optically isolated, constant current unit for
DC and pulsatile stimulation procedures. It is particularly
useful for low current applications in the range of 0.1 to
1.5 microamperes.
