#CMT# #/CMT# The device has a connector (3) including pins (5, 6) movable with respect to each other, and a pre-recorded measurement table (14) containing pre-recorded measurements which correspond to space parameters. Each measurement corresponds to a value of impedance brought by the pins based on a space (13) between the pins during impedance measurement. A measuring apparatus (1) has a processing circuit for producing a measurement of impedance between the two pins based on one pre-recorded measurement corresponding to an effective space during the impedance measurement. #CMT#USE : #/CMT# Device for measuring an impedance between two points of a high frequency circuit or very high frequency circuit e.g. printed circuit and monolithic integrated circuit (all claimed), of an electronic component e.g. capacitor. #CMT#ADVANTAGE : #/CMT# The processing circuit of the measuring apparatus produces the measurement of the impedance between the pins based on the pre-recorded measurement corresponding to the effective space during the impedance measurement, thus eliminating the need for modifying the measurement chain, and ensuring better flexibility in utilization of the connector for standard measurements, while controlling the influence of the connector on the measurement, and hence producing a reliable and interpretable result in the impedance measurements. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an impedance measuring device. 1 : Measuring apparatus 2 : Cable 3 : Connector 5, 6 : Pins 13 : Space 14 : Pre-recorded measurement table. |
