Automatic compensation system for impedance measurement

Automatic compensation system for impedance measurement

This paper deals with the realization of the four-pair terminal definition of impedance standards. A simple, though reliable, system is described that allows an automatic compensation of the voltage at the low potential port of impedance standards to be obtained. Such a system employs a commercial data acquisition board and a signal generator with adjustable-phase capability, which acts as the ...

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

A Cell Impedance Measurement System

A cell-impedance measurement system is presented that can measure an effective parallel resistance and capacitance of a cell to within 1% in 1ms. It is proven to be functional at ten logarithmically-spaced frequencies between 100 kHz and 100 MHz, with ten parallel structures simultaneously calculating each of these. This system is further shown to be implementable with commercial parts – namely...

Input impedance antenna automatic matching system

This paper presents a new design for an input impedance antenna automatic matching system. In order to achieve this main objective, it is necessary to accomplish several intermediate tasks. On the one hand, a study about the implementation of a generic electronically tunable impedance synthesizer is carried out. Then, a prototype based on the research is constructed, and its characteristics and...

Programmable Digital Bio-Impedance Measurement System

The field programmable gate array is the fastest growing technology. The bio-impedance measurement system is implemented in reconfigurable field programmable gate array hardware. The design of bio-impedance measurement system using Xilinx system generator is more convenient and cheaper for revising, if the Bio-impedance measurement system requires parameters changes in practical use, since no n...
