The depth of the impulse is given for one peak of the wave, so at its maximal value one pulse gives
4*400=1600 of simulation (using the four peaks of the pulse).
At 100Hz this means that during 1 sec a total of 100*1.600=160 msec is the time of stimulation,
which gives a D=16% duty cycle.
8.1.3 Measurements
The measured values of the preset stimulation parameters are within a ±5% range of the preset
values. This holds for the stimulation times, the frequency, the impulse depth and the amplitude as
well. Only the amplitude can differ from this because there is a current regulation on the output
channels thus the voltage can be lower than expected to provide safe stimulation. The hardware
protection is detailed in the following section.
The values are 100 % accurate expect the frequency, which has

The output parameters seen below are measured done using a 500 , a 2000
resistance, respectively. The maximum power density is measured using the smallest electrode ("L"
shaped).
