9.1.2 Neuro-Stimulation Parameters
All electrical specifications are given for an impedance of 500-1,000 ohms per channel.
9.1.3 RF data
The Wireless Professional may be aected by other devices even if they are compliant with CISPR
EMISSION requirements.
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 999 (energy) in
minimum increments of 0.25 mA.
Pulse width: 30 to 400 s.
Maximum electrical
charge per pulse:
96 micro coulombs (2 × 48 C, compensated)
Standard pulse ramp-up time: 3 s (20 %-80 % of maximum current)
Pulse frequency: 1 to 150 Hz.
Transmission and reception
frequency:
2.4 [GHz] ISM (2.4-2.4835 GHz)
Characteristics of the
modulation type and frequency:
GFSK, +/-320 [kHz] deviation
Eective transmission power: 4.4 [dBm]
