Course data
- Course name: Computer Controlled Measurements
- Neptun code: BMETE11AF38 (old code: BMETE11AF10)
- Requirements: 0/0/2/F/3
- Language: English
- Responsible lecturer: Dr. András Halbritter
- Instructor: Gergő Fülöp
- Requirements to pass:
- Completion of programming exercises (first 2 classes).
- Passing the written short tests and completion of all the measurement control exercises. In case of justified absence, you have the possibility to retake 2 experiments.
- Handing in reports of the exercises within the deadline.
- Each test and report must have at least a pass (2) grade.
- Grading:
- Short tests before each measurement control exercise (max. 20 pts each)
- Reports (max. 100 pts each)
- Total: 480 pts, the final grade is determined as per the table below,
- < 40%: fail (1)
- 40% - 55%: pass (2)
- 55% - 70%: satisfactory (3)
- 70% - 85%: good (4)
- 85% < : excellent (5)
- In case a report, measurement control program or written test is not the result of independent work, it will automatically be evaluated to be the maximum score multiplied by negative one, regardless of the degree of copying.
Overview
The participants gain experience in computer controlled measurements and in the programming of scientific instruments and data acquisition system. To this end the following topics are covered: communication with the instruments via serial, GPIB, and USB ports. Programming of data acquisition cards. Programming of complex measurement control platforms, plotting and saving the data, programming of timelines, in-situ data analysis. The course consists of 4 hour-long computer laboratory exercises every second week. In the first part of the semester fundamental programming skills are obtained through simple example programs. In the second part the participants individually program complex measurement control and data analysis platforms, like nonlinear curve fitting by Monte Carlo method, full computer control of a digital multimeter, digital oscilloscope program using a data acquisition card.

The report and the source code of the measurement control program must be submitted until Sunday midnight, on the week of the measurement, as an Assignment in MS Teams. The Visual Studio project directory should be zipped and attached to the MS Teams Assignment, along with the report in PDF format. The language of the report is English or Hungarian.
Installing Visual Studio
We use Visual Studio 2017 in the lab computers. For working on your own PC, download and install the Community edition of Visual Studio 2017 or 2019 from the link below:
https://visualstudio.microsoft.com/vs/older-downloads/
You should install Visual Studio with .NET workload.
Installing NI DAQmx
In case you would like to use your own PC for working with the myDAQ card, you also need to install the NI-DAQmx library. Download and install it from here: https://www.ni.com/hu-hu/support/downloads/drivers/download.ni-daqmx.html#348669
The installer has a lot of options. You will need NI MAX (Measurement & Automation Explorer), and .NET 4.5 support.

Measurements
There are 4 measurements for the semester:
- Using a data acquisition card (myDAQ1)
- Curve fitting with a Monte Carlo method (Monte Carlo)
Students have to take a short written test before each measurement.
