Hello all, I am looking for background information on the rationale behind the conducted immunity test levels defined in EN 55035 / CISPR 35 and IEC 61000-4-6.
Specifically, in 55035:2016 table 2, clause 2.1 calls for a test level of 3V rms from 0.15 to 10MHz. It also defines a slope that reduces the signal level above 10MHz. What is the technical rationale behind 3V rms being the desired immunity level for ITE equipment? Second, why does the voltage level taper above 10MHz in 55035, as opposed to 55024, where the test remains constant from 150kHz - 80MHz? IEC 61000-4-6 also calls for 1V, 3V, 10V rms test levels and calls for 80% AM modulation "to simulate actual threats". Is the rationale behind this documented somewhere? What threats were considered? I suspect this is a rabbit hole, but curiosity (and a concerned client) has gotten the best of me. -- Jeff Keyzer MightyOhm LLC j...@mightyohm.com - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
