By reading ICNIRP directives whose EC 2004/40 directive is based on, I have understood so far there are three main methods for evaluating exposure limit conformity:
-> *equivalent frequency method* (applicable for isolated pulses and burst signals),
-> *standard method*, most effective for incoherent signals,
-> *weighted peak method (the latter introduced in 2003 and the most versatile one because it takes into account phases of present harmonics)*.

Both the standard method and the weighted peak measurement methods end up producing an numeric value, which shall be below one in order for the emission to be below ICNIRP limit. Infact, conformity to ICNIRP frequency limits in low frequency ranges up to 100 kHz is NOT by simple comparison between the measured signal spectrum and the ICNIRP frequency mask. Instead, in the standard ICNIRP method, a sum of contributions must be made, where each contribution is the ratio between the measured amplitude at a given frequency and the ICNIRP limit at the same frequency.
Additionally, no RMS averaging over time must be performed at low frequency, according to ICNIRP.

What of the above ICNIRP assessment methods does NF-5030v4 support?

If you want to perform complex ICNIRP measurements you need to use our free MCS software which offer all needed features and settings.
