A virtual instrument to test smart transducer interface modules (STIMs)

This paper reports the hardware and software of virtual instruments and the tests conducted on a microcontroller-based smart transducer interface module (STIM) to check both STIMs performance and the suitability of a network capable application processor (NCAP) implemented in LabVIEW. The tests include the characterization of a digitizing channel of the STIM and the performance analysis of the system when the STIM simultaneously operates its digital outputs and its analog inputs.
