During Radiated Emission test i encountered a huge peak around MHz on Electrical field, where the quasi peak margin (db) is above the Quasi peak margin limit however the test failed. What would be the main reasons for the failure on DUT

Primary cause of failure was likely a combination of the weather and phase of the moon. The perfect storm.

You have presented absolutely no data or numbers or even what was tested, test methods and procedures so how can you expect an answer to main reason for a cause of failure? Details really go a long way in getting good answers.

was this the cause?
