Mazda BSD Tx Chip  BSD – Blind Spot Detection  The device is a 24 GHz radar  It is mounted in the rear bumper of the car  Warns the driver when there are vehicles in the blind spot of the side-view mirror  Lane changing in the city and on highway becomes safer 13

Mazda BSD Tx Chip  How it works 14

Mazda BSD Tx Chip  PWM controlled antenna problem solved immediately using data acquired by the ATS 15

Conclusions:  Tests and validations of ECUs in short time  Complying automotive standards  High reproducibility for tests  Lower costs for next developed ATS 16
