ABSTRACT:
A measuring device, with a digital interface for the transmission of digital signals to an evaluation unit, is disclosed, whereby the interface includes a clock input, to which a system clock signal is fed, a signal input, to which a measured signal is applied, an arithmetic unit, which derives an output signal from the clock signal and measured signal, and a signal output where the output signal is output and transmitted to the evaluation unit. Measurement accuracy may be improved by transmitting a reference signal that is a signal derived from the clock signal, and using this reference signal to correct the output signal.
