Purpose and area of application

   On the faculty of radiophysics and electronics of the Grodno State University of Y.Kupala was developed a measuring and control complex on the base of the personal computer, optimized for a modern laboratory practical work in universities, colleges and schools. On the base of the developed complex and corresponding software there were created laboratory trainings on subjects of theoretical bases of electrical engineering, radio engineering circuits and signals, electronic and semi-conductor devices, amplifiers.

Advantages

The complex allows
  • to replace set of standard measuring devices: generators, oscillographs, voltmeters, frequency gauges, phase gauge, analyzers of a spectrum, statistical analyzers, etc.
  • essentially to expand opportunities of the device it is possible by connection of various gauges, converting physical sizes into electric signal (movements, positions, acceleration, temperature, pressure, illumination, etc.), to analog or digital inputs. Laboratory practical works on mechanics, molecular physics, chemistry, biology in this case can be realized.


Requirements to the computer

CPU 400 MHz, RAM 64 Mb, operational system WIN98/2000/XP.
