The system consists of two independently operating power modes – pulsed or DC (continuous mode). The maximum average power delivered by the sensors output is 50 W in pulsed mode, or 80 W in DC mode. This specification is linked to the external power probes used. The voltage measurements on the two channels are carried out from the internal resistance of each channel. The current measurements are made using differential measurements at the terminals of the same internal resistance.
