Greetings and Happy New Year,
I have a question on the definition of physiological parameter. Specifically
on how it is used to determine the modulation frequency for radiated and
conducted RF immunity testing as specified in IEC/EN 60601-1-2:2001.
Clause 36.202.3 b) 3) indicates the method of amplitude modulation. To
summarize: The modulation frequency is to be 2 Hz for equipment and systems
that monitor, measure or control a physiological parameter. 1000 Hz
modulation for all other equipment.
I am trying to determine if 2 Hz modulation should be applied to MRI systems
and components.
Interpretation of the standard is welcome, but a specific reference on how to
apply the clause would be very helpful.
Thank you,
Michael Peters
