SG 3000

SG 3000 systems are dedicated to full-scale vehicle antenna measurements and OTA testing.The system configuration can be adapted to meet specific needs and to fit your installation: different arch sizes can be designed, and its structure can be fixed (F) or mobile (M) allowing it to be either permanently installed or moved into an existing anechoic chamber. The rotation of the DUT is controlled by a high precision positioning system enabling discrete and/or continuous on-the-fly measurements.

An SG 3000 system is used for the measurement of antennas placed anywhere on a vehicle. It uses Analog RF Signal Generators to emit EM waves from the probe array to the Antenna Under Test or vice versa. It uses the N-PAC as an RF receiver for antenna measurements. The N-PAC also drives the electronic scanning of the probe array. The Amplification Unit has RF amplifiers for each of the RX and TX channels. For OTA measurements, the tests are performed through the radio communication tester. The amplification units amplify the signal on transmission/reception channels to achieve optimum dynamic range. The Transfer Switching Unit is used to switch between the emission and reception modes of the DUT.
