Measurement Technique

Course Description

Fundamentals of measurements. Analogue and digital instruments: application and restrictions. Instruments with A/D converters. Quantisation principles. Transfer function and quantisation errors. Dual slope analogue to digital converters, voltage to frequency converters, Σ-Δ converters. Parameters of the converters, restrictions and uncertainty in measurement. Digital to analogue converters: transfer function and codes, parameters. Programmable devices and interfaces. Digital instruments (multimeters, multichannel, precise, electrometers): parameters and interpretation of the results. Interfaces for parallel transmission: GPIB (IEEE-488), VMEbus/VXIbus and PXI interface. Interface control and programme. Drivers for measuring instruments (SCPI, IVI, VISA). Accuracy and influencing quantities. Intererence and shielding. Noise and its cancellation. Measurement of low dc voltage and current. TEMS. Measurement of low and high impedances. Resistivity measurement of (semi)conductive materials. Applications.
