Form of the currents
Two-phase rectangular pulses
The current is symmetrical biphasic with zero mean: the positive and negative pulses are of the
same amplitude and duration
The waveform is constant current and does not depend on the value of the load.
The pulse width is adjustable from
15µs to 10ms
, the frequency is adjustable from
1Hz to
5kHz
.
LF modulation (1Hz to 500 Hz) of the signal is possible.
The device complies with standard 60601-2-10: Medical electrical equipment: special
requirements for basic safety and essential performance of nerve and muscle stimulators. In
particular, this standard limits the delivered intensities as well as the powers per pulse.
Envelope generation :
The pulse signal is included in an envelope allowing a progressive application and cut-off of the
current
Peak amplitude (mA)
Pulse width (µs)
Signal period = 1 / Frequency (in Hz)
