        Electromagnetic compatibility
Figures
1 Test signal for subclause 6.3.1 at a frequency of
        500 kHz and for subclause 6.3.3 at frequencies
        above 150 kHz
2 Low-pass filter to separate spurious low-
        frequency signals
3 Test set-up to check the interference generator
        for spurious low-frequency noise and to determine
        the appropriate capacitor Cx
4 First tissue interface equivalent circuit for
        current measurements
5 Test set-up for measurement of induced current
        flow
6 Second tissue interface equivalent circuit to
        check for malfunctions
7 Test set-up to check for malfunctions
8 Test signal for subclause 6.3.3 at frequencies
        below 150 kHz
9 Test set-up for magnetostatic measurements
