Radiated Immunity Test for Platform Screen Door(PSD) Sensors Using Broadband Signals

With the advancement of mobile communication technologies, the use of smart devices, including mobile phones, has increased. To accommodate the growing data capacity, digital modulation techniques such as OFDMA are being used across wide frequency bands. Despite the rise in malfunction cases caused by these broadband signals, current radiated immunity tests are conducted using AM signals based on IEC 61000-4-3 standards. This paper proposes a testing method utilizing mobile communication broadband signals to address the recent malfunction issues of Platform Screen Door (PSD) sensors and verifies the impact of these broadband signals
