NETELAB
hardware platform for educational research laboratory works
on physics, electrotechinic and electronics related disciplines

 

Application

Equipment set NETELAB is designed to provide studying of various physical phenomena, characteristics and behavior of electronic circuits and schemes, and to give basics and grow a skills in practical work with modern measurement equipment. Set includes one or some individual workplaces.

Each workplace consist of instrumental unit (includes 2 PSUs, 2 signal generators, digital voltemeters, phasemeter, digital oscilloscope and curve-tracer) and measurement unit (allows to assembly various electrical and electronic schemes).



 

Essential features

Operational mode of NETELAB by default is autonomous. Provided a functionality for equipment control and data transfer through LAN, which allows a teacher to monitor student’s activity and work progress.

NETELAB’s features:

  • rugged design of operator controls;
  • possibility to limit signal parameter’s ranges and certain devices blocking to prevent equipment damage if laboratory work is carried by newbies
  • complexing of measurement and generating tools to provide operation of NETELAB as multifunctional curve-tracer allowing to demonstrate experimental characteristics curves
    uВХ(f), uВЫХ(uВХ), uВХ(iВХ) to intensify studying process of frequency response, resonance phenomena, nonlinear elements characteristics and various circuit, containing nonlinear elements
  • results deminstration on common presentation display equipment (optional)
  • resulting oscillogram images transfer through wireless network (optional)
