Electronic Measurement Systems
FEKT-LEMSAcad. year: 2017/2018
The course deals with technical resources for measurement automation. Basic solutions for measurement systems’ design assembled from both specialized instrumentation and universal components is explained. Attention is especially focused on designing a system that meets the specified requirements, selection of suitable components and software implementation issues.
Learning outcomes of the course unit
Graduate student knows:
- terminology of measurement systems,
- basic modular systems for automation of measurement and corresponding standards.
Graduate student can:
- perform theoretical design of the measurement system,
- determine sources of uncertainty in the measurement system,
- create simple measurement system including software implementation (NI LabVIEW),
- determine requirements for the robustness of the system and its operation.
Knowledge in the Bachelor's degree level and basic usage of the development environment NI LabVIEW is required.

Planned learning activities and teaching methods
Teaching methods depend on the type of education which are described in the Article No. 7 of the Study and Examination Regulations of BUT. Teaching methods include lectures and laboratory work.
Assesment methods and criteria linked to learning outcomes
Up to 40 points for laboratory exercises where students can earn up to 24 points for laboratory work and up to 16 points for one individual project. Credit is given for delivery of a project and gain of minimal 5 points from laboratory work.
Up to 60 points for the final written exam.
Language of instruction
1. Introduction, course content, basic terms.
2. Theoretical foundations of automation of measurement - the characteristics of the measurement chain, measurement uncertainties in automated systems (CSN EN 60359).
3. Terminology, structure and requirements for measurement systems (virtual, modular).
4. Analog circuits in measurement systems (A/A, A/D, D/A converters).
5. Sampling and its properties, aliasing effects and its limitations, multichannel data acquisition.
6. Basic components for measurement systems consisting of specialized equipment.
7. Universal hardware for data acquisition, analysis and processing.
8. Modular measurement systems (PXI, CompactRIO).
9. Communication between measurement instruments and PC (RS232, GPIB, USB, Ethernet).
10. Language for communication with measuring instruments (SCPI).
11. Software tools for measurement systems and virtual instrumentation.
The course goal is to familiarize students with the process of design and implementation of measurement systems. Student will learn to work with common measurement systems and understand the problems of measurement automation. Student is able to choose an appropriate concept of measurement system, assemble it and determine its measurement uncertainty. He knows the way of description of the general properties and structure of the measurement system.
Specification of controlled education, way of implementation and compensation for absences
Participation in laboratory exercises is not mandatory excluding the first exercise. Assessment is based on submission of one project and evaluation of student activities in the exercises during the semester.
