EMIC Unité à micro-ondes, Contrôlée par Ordinateur (PC)
The Computer Controlled Microwave Unit, "EMIC", designed by EDIBON, allows to study different microwave waveguide configurations for introduce students the main concepts about microwave communications through waveguide and antennas systems.
The Computer Controlled Microwave Unit, "EMIC", integrates a microwaves measuring test bench formed by microwaves generator, a kit of different standardized (WR-90) waveguides devices (horns antennas, attenuators, etc), measure devices (Power meter, Slotted line, etc), an Control interface box to connect to the computer and a software for data acquisition and parameters calculation.
This unit includes different components to conform many configurations of the microwave test bench, including an aerial microwaves link, Hybrid Tees's configurations, determination of unknown impedance, etc, all of them are full explained in the set of practices.
The "EMIC" allows the familiarization and experimentation with essential measurements in microwaves systems: power emission, attenuation, matched and mismatched loads, gain of a horn antenna, frequency, wavelength, stationary wave r a t i o (SWR), impedance, operation with Smith chart, etc.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
