Abstract:
The article aims to consider the use of virtual laboratories as a tool for training, teaching, and research of various simulation schemes and models in university courses in electronic measuring the conditions of COVID-19.

Existing modern university engineering education must quickly and adequately adapt to the conditions of the COVID-19 pandemic, which requires the use of adaptive and universal tools and means for accessible teaching of engineering disciplines at a distance. For this purpose, virtual laboratories can be used effectively in bachelor's and master's courses.

This type of laboratory is aimed at increasing students' interest and easier perception of the fundamental theoretical concepts by performing observations, research, and experiments from a distance.

Virtual labs provide students with unlimited access to certain models, as well as their effective participation and remote control of experiments. These laboratories also provide students with effective interaction with a real object of research.

Virtual labs are an effective graphical user interface through which during the work students can observe what is happening on the screen, simulate impacts on existing virtual buttons, switches, controls, and in certain libraries to use various measuring instruments needed to perform the specific task. With the help of measuring instruments, students can immediately make the necessary analytical and graphical analyzes of the results obtained. In this way is created the logical and abstract thinking of the students.

Various environments can be used as virtual laboratories, such as analog circuit modeling environments - Spice, Gnucap and their derivatives, as well as HDL environments. Although these are more design tools, HDL can also be used for teaching and experimentation by students. Modern Spice derivatives offer a wide range of components and libraries. At the same time, they have an intuitive interface for quick and easy assembly of circuits and their simulation.
During the simulation in the virtual laboratory, students have the opportunity to observe voltage diagrams at each point of the simulation circuit, as well as currents in each circuit.

Another environment is LabView, which contains a large set of tools and libraries and is easy for students to use.

All environments that can be assigned to virtual laboratories are a kind of complex development environment, but can also serve as a good tool for studying the characteristics of the relevant elements in the simulation scheme or model. Students regularly use this type of environment to find answers to their questions. This is a pandemic situation, but not always a good option, but the use of virtual laboratories - solves this problem.

The use of virtual laboratories in electronic measuring equipment in the conditions of COVID-19 is necessary for engineering education, which allows students to better understand the basic scientific and engineering concepts by performing experimental research from a distance. This is extremely useful and necessary for their development in this field of science.
