REVOLUTION WIRELESS™
9.1.2 Neuro-Stimulation Parameters
All electrical specifications are given for an impedance of 500-1,000 ohms per channel.
Outputs:
Four independent and individually adjustable channels that are
electrically isolated from each other.
Pulse shape:
Constant rectangular current with pulse compensation to eliminate
any direct current component to prevent residual polarisation at skin
level.
Maximum pulse intensity:
120 mA.
Pulse intensity increments:
Manual adjustment of stimulation intensity from 0 to 120 mA
(intensity) in minimum increments of 1 mA.
Pulse width:
30 to 400 μs.
Maximum electrical
charge per pulse:
96 micro coulombs (2 × 48 μC, compensated)
Standard pulse ramp-up time:
3 μs (20 %-80 % of maximum current)
Pulse frequency:
1 to 100 Hz.
