Training objectives
- The aim of the course is to provide a comprehensive introduction to the digital and analogues instrumentation typically used in research and development laboratories. In addition, the course deals with the basic concepts for evaluating and expressing the measurement uncertainty.
Main acquired knowledge:
- Ability to evaluate and report the measurement uncertainty.
- Working principles of analogue and digital instrumentation.
- Measurement techniques used for device and circuit characterization under static and dynamic operation.
- Basics of programming for automatic control of measurement systems.
Main acquired skills:
- Use of laboratory instrumentation (i.e., oscilloscope, spectrum analyser, digital multimeter, function generator, power supply).
- Characterization of electronic devices (e.g., diodes, transistors) and circuits (e.g., amplifiers, oscillators) under static and dynamic operation.
- Ability to make a reasoned choice of suitable instrumentation and measurement technique for a particular application.
- Ability to set-up a measurement system with interconnected instruments and to develop its control software. Prerequisites
- The following concepts, in addition to the knowledge provided by the course of “Electrical circuits: fundamentals and theory,” are required:
- Basic concepts of probability theory.
- Basic concepts of digital and analogue electronics. Course programme
- The course consists of 60 hours of teaching, divided into lectures and guided laboratory experiences, distributed as follows:
- Introduction (2.5 hours)
- Measurement uncertainty (10 hours)
- Digital multimeter (5 hours)
- Digital storage oscilloscope (5 hours)
- Spectrum analyser (5 hours)
- Signal sources (2.5 hours)
- NI LabVIEW (15 hours)
- Laboratory sessions (15 hours) Didactic methods
- The subjects related to the evaluation of the measurement uncertainty and the theoretical study of the measurement instrumentation will be addressed with:
- video-lectures on the topics of the course delivered weekly.
- weekly focus groups in which theoretical topics will be reviewed also by means of exercises and practical demonstrations.
The lectures on NI Labview programming will be held in presence in a Computer Science Laboratory. Video-lectures from the previous academic years will be made available as support material.
The practical experiences on the use of measurement instruments will be held in the Electronics Laboratory. A lecture note will be provided for each experience to guide the student through the activity. A video-summary will follow some of the experiences to summarize their main contents. Due to the limited number of workstations in the laboratory, students may have to participate in groups of 2/3 people spread over several shifts. Learning assessment procedures
- The exam consists of 3 written tests to take on the same day:
1. questionnaire with open-ended questions on measurement instrumentation (11 points, available time: 1h 30m)
2. questionnaire with multiple choice or short-answer questions on programming in the NI LabVIEW environment. (11 points, available time: 45m)
3. exercise on the calculation of measurement uncertainty (11 points, available time: 1h)
The 3 tests allow a total of 33 points. The exam is passed if each test is passed and the student achieves a minimum score of 18 points overall. A score higher than 30 points provides the honors.
Partial results will not be maintained for any reason.
It is not possible to consult texts, notes or any other material during the exam.
For organizational reasons, the exam list closes two working days before the date of the exam. Reference texts
