Dear,
good day!
we use ZSSC3224 and MEMS bridge sensor to assemble pressure sensor. The result is excellent in basic function. But when we do the Radiated Susceptibility test, we find some issue.
we select the I2C communication to read sensor output. the I2C communication is OK during whole test period.
The issue is pressure readout.
Under 28 V/m strength, the output is OK when the frequency below 1.7GHz. exert 1.7GHz and above RF interference, the deviation (MAX-MIN) is around 2.4mmHg.
Can you tell me the reason why the pressure changes a lot in high frequency RF interference? How do I solve this RF interference issue?
Waiting for you help!
Best Regards,
Jarvis
Hello Jarvis,
Thanks for your request.
Please let us check this and get back to you as soon as possible.
Could you please check your private message and reply to me?

Hi Jarvis,
every electronic device is sensitive to electromagnetic radiation, the only question is at what level of interference do functional impairments begin to occur.
Please refer to the following document:

Even ther is another product in focus the basic principle is the same.

Dear Kornelius,
many thanks for sharing the EMC document.
