EMI マイクロウェーブ 演習装置



The Microwave Unit, "EMI", 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 Microwave Unit, "EMI", integrates a microwaves measuring test bench formed by microwaves generator, a kit of different standardized (WR-90) waveguides devices (horns antennas, attenuators, etc) and measure devices for complete the set of practices (power-meter, slotted line, etc).

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 "EMI" unit 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 (SWR), impedance, operation with Smith chart, etc.
