NTC-03.04.B “Radio engineering and telecommunications”

Constructively the training laboratory equipment consists of the basis and interchangeable panels. The basis contains a measuring system, a signal generator and a power supply unit. The basis can be supplemented by different sets of interchangeable panels, which allow the regulation in accordance with the curriculum of the educational institution to be conducted. Additional necessary modules can be bought in future in case the list of laboratory works changes. The basis is performed in desktop design.

The interchangeable panel is a printed circuit board with graphical conventions and the inner structure of the subject on its frontal side. Switchboard jacks, controllers and tumblers are also installed on the panel. During the experiment the interchangeable panel is connected to the basis. The equipment is intended for work with a PC or a laptop.

Software and methodical documentation supplemented to the equipment:

• methodical and technical documentation set intended for academic staff;
• student testing program for laboratory work authorization, which tests both theoretical knowledge and the knowledge related to the laboratory work contents and gives marks.

Measuring system software allows the following operations to be conducted:

• output of 2 measuring channels on the same coordinate axes with individual vertical tuning of scale parameters for each of them and with common horizontal tuning of scale parameters for all channels;
• spectrum analysis of any measuring channel;
• registering amplitude-frequency response in manual and automatic modes;
• measuring signal parameters on any of the channels used.
