mpylab.limits.radiated_emission.fcc_part18_subpartc module

Radiated-emission limits according to FCC Part 18.305 (Subpart C).

mpylab.limits.radiated_emission.fcc_part18_subpartc.FCC_PART18_305

alias of LIMIT

class mpylab.limits.radiated_emission.fcc_part18_subpartc.LIMIT(case=None, distance=None, operating_frequency=None)

Bases: _Part18

Configurable FCC Part 18.305 radiated-emission limit model.

Parameters:

• case (str, optional) – Existing equipment-case selector.

• distance (str, optional) – Existing measurement-distance selector, default 30 m.

• operating_frequency (float, optional) – Actual device operating frequency in Hz. Required to establish a radiated exemption in its associated ISM band. Missing context keeps such an assessment unresolved. Legacy pickles without this attribute are treated as missing context.

Raises:

ValueError – For unknown selectors, invalid operating frequency or a contradiction between the miscellaneous case and the operating frequency.
