Hello! I would like to confirm about the testing of FT/B(EN61000-4-4). Do we need the synchronization test, although there is no description which takes a synchronization about the phase angle of a power supply according to the standard document?
Since the test is injected at every 300ms by a unit of 15ms, it will always be injected on the same position of power supply frequency of 50Hz(in 75%). In other word, it will not be injected on the same 25% position. (50Hz = 20ms) I don't know this result is important thing or not. Please give me a comment.
