- ETM: Computer Controlled GSM Communications Unit
A cellular mobile trainer that works with a computer through a USB connection. Students see the AT commands exchanged with the SIM card as each mobile service is used, and study how SIM memory is managed for the SMS inbox and phonebook.
- EMI: Microwave Unit
A microwave measuring test bench with an electronic console, microwave generator and a kit of standard WR-90 waveguide devices. Students carry out measurements of power, attenuation, load matching, horn antenna gain, wavelength, standing wave ratio and impedance.
- ESA: Computer Controlled Satellites Unit
A computer controlled trainer for satellite telecommunication systems. Three blocks reproduce the ground transmitter station, the active satellite repeater and the ground receiver station, so students can follow the uplink and downlink signal chain and insert faults.
