Industrial, Scientific and Medical Equipment (CISPR 11)
The standard applies to information technology equipment (ITE) as defined in section 3.1.
Procedures are given in AS/NZS CISPR 22 for the measurement of the levels of spurious signals generated by the information technology equipment (ITE) and limits are specified for the frequency range 9 kHz to 400 GHz for both Class A and Class B equipment. No measurements need be performed at frequencies where no limits are specified.
The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.
