Laboratory device for electric and electronic circuits study by the means of virtual measuring instruments is intended for vocational education and training institutes of all levels (school, colleges, institutes and universities).

 "Gloria" laboratory device:
 "Gloria" laboratory device components:

The device consists of "Gloria" base station, a set of circuit boards(12 boards), personal computer and software. Virtual measuring instruments were developed via LabVIEW software and they are displayed on a computer monitor. Main measuring instruments are dual-channel oscilloscope and pointer-deflecting instrument (amperemeter, voltmeter of direct and alternating current).

Oscilloscope is the main instrument for study of electric circuits with    non-sinusoidal exposure. Its front panel is almost the same as real oscilloscope  panel. This makes it possible for easier studying of real devices instruments process.

Conducting of study

For researches circuit board with selected scheme is plugged into the base station. Researchers via control components enter required parameters of input signals (shape, frequency, voltage) and take measurements at various scheme point. Research results in a view of oscillogram and instrument indications are recorded in separate computer file.

For easier measurements each circuit board has electrical schematics on it.
