Abstract

An implementation ofthe sine-approximation method of ISO 16063-11 is described. The quadrature interference signals are generated using an interferometer as described in method 3 of ISO 16063-11. The signal processing required for the successful implementation of this method of ISO 16063-1 1 has been implemented by various Metrology Institutes using various techniques. For the implementation of these techniques, different hardware and software configurations are used, ranging from expensive VAX computer systems to digital storage oscilloscopes. A novel, cost effective, fully PC based system has been developed and is described here-in. The hardware consists of a Pentium 200 with 256 MB of RAM. A commercial, 4 channel AtoD card is used for performing the data capturing, while the signal processing software was developed to run under Microsoft Windows®.
