Patent ID: 8131896

Claim:
A signal converter that connects a measuring instrument for conducting a predetermined measurement and outputting a measurement signal obtained by the measurement with a signal processor for processing the measurement signal and transmits to the signal processor a signal outputted by a first communication interface provided on the measuring instrument after converting the signal in a signal transmission format capable of being inputted to a second communication interface provided on the signal processor, the signal converter comprising: a first communication unit that has the first communication interface; a first signal conversion unit that converts the measurement signal in a signal format according to a first communication protocol that is processable by a first driver installed in the signal processor; a second signal conversion unit that converts the measurement signal in a signal format according to a second communication protocol that is processable by a second driver installed in the signal processor; a conversion controller that selects one of the first signal conversion unit and the second signal conversion unit, selected one of the first and the second signal conversion units performing the conversion of the measurement signal; and a second communication unit that has a second communication interface that is capable of being connected with the signal processor, the second communication unit outputting the measurement signal.
