1. A measurement device comprising:
at least two measurement signal inputs forming consecutive pairs of signal inputs;
at least two multi-channel analog-to-digital converters, each multi-channel analog-to-digital converter comprising two ADC signal inputs, each one of the two ADC signal inputs being configured for coupling the respective multi-channel analog-to-digital converter to one of the at least two measurement signal inputs and being selectively operable on a single signal received to one of the ADC signal inputs in a high-speed interleaved operating mode or on two signals received at the same time to the two ADC signal inputs in a lower-bandwidth non-interleaved operating mode;
wherein each one of the at least two measurement signal inputs of consecutive pairs of signal inputs is coupled to a different one of the multi-channel analog-to-digital converters, and
wherein, while in the high-speed interleaved operating mode, each multi-channel analog-to-digital converter is configured to switch from the high-speed interleaved operating mode into the lower-bandwidth non-interleaved operating mode responsive to receiving the two ADC signal inputs of the respective multi-channel analog-to-digital converter.
