AWGN modulation correspondence! Conducting proximity tests with wideband interference waves.
The "Antenna Proximity Immunity Test" is a test that evaluates the resistance of electronic devices by using antennas designed for immunity to nearby electromagnetic fields, generating strong electric fields for each frequency of interference wave. In the field of automotive EMC, it is standardized as ISO 11452-9 (Portable Transmitters). Our organization has restructured and implemented the antenna proximity immunity test system to accommodate not only the modulation conditions of interference waves specified in the standard, such as AM (Amplitude Modulation) and PM (Pulse Modulation), but also the AWGN (Additive White Gaussian Noise) modulation added in ISO 11452-9:2021. 【Target Applications】 ■ Bluetooth, WLAN (data), Wi-Fi ■ LTE (mobile devices using OFDMA and SC-FDMA) ■ IEEE 802.11a (5GHz band Wi-Fi) *For more details, please download the PDF or feel free to contact us.
