The Computer Controlled Antenna Unit, “EANC”, is an advanced system that operates in conjunction with a computer (PC), which allows the control and data acquisition of the antenna measurement by means the SCADA System (control interface box + control software).
The “EANC” performs the full-automatic 360° rotation of the transmitter antenna tower, controlled by the software, for draw the antennaradiation pattern and display it in the computer (PC) window.
The “EANC” also allows the full automatic frequency sweep in order to perform the bandwidth analysis of an antenna.
