Instruments Systems and their Programming

Lecturer:

Tutor:

Supervisor:

Department of Measurement

Synopsis:

Connection of measuring, diagnostic and monitoring instruments to a PC (including notebooks), their integration into DAQ systems. Connection of smart sensors to these systems. Programming of DAQ systems on the user level. Virtual instrumentation for biomedical application. Integration of measuring, diagnostic and monitoring systems into local nets. Labs are aimed at programming the systems mentioned above using different developing tools.
