A DSP based VXI instrument for impedance measurement
Leopoldo Angrisani, Aldo Baccigalupi, Antonio Pietrosanto · 2002
A VXI instrument for impedance measurements, equipped with a TMS320C30 Digital Signal Processor, is presented. The paper is the evolution of a previous work describing the realization of an impedance meter prototype. After a brief summary of the measurement techniques, already described in the previous work, the hardware architecture and the software strategies adopted in the VXI instrument implementation, mainly intended for the use in industrial environment, are described in detail. Experimental tests for a wide range of impedance values are then carried out for the instrument metrological characterization and throughput evaluation. Concluding remarks are finally reported.
