5.1 General

The following information shall be recorded in or annexed to the test report:

– The primary functions of the radio equipment to be tested during and after the EMC testing;

– The intended functions of the radio equipment which shall be in accordance with the documentation accompanying the equipment;

– The method to be used to verify that a communications link is established and maintained;

– The user-control functions and stored data that are required for normal operation and the method to be used to assess whether these have been lost after EMC stress;

– The ancillary equipment to be combined with the radio equipment for testing (where applicable);

– The information about ancillary equipment intended to be used with the radio equipment;

– Information about the common and/or band-specific active RF components and other hardware blocks for a communication link in EUT capable of multi-band operation;

– An exhaustive list of ports (or RIBs), classified as either power or signal/control. Power ports shall further be classified as AC or DC power.

Performance assessment of a NR repeater with multiple enclosures may be done separately, according to the manufacturer’s choice.

A communication link used by more than one operating band, shall be assessed on all operating bands. Communication link(s) and/or radio performance parameters for the operating bands can during the test be assessed simultaneously or separately for each band, depending on the test environment capability.

5.2 NR repeaters

The parameter used for assessment of performance of a NR repeater is the [gain] within the operating band.

5.3 Ancillary equipment

At the manufacturer’s discretion the test may be performed on the ancillary equipment separately or on a representative configuration of the combination of radio and ancillary equipment. In each case EUT is tested against all applicable immunity and emission clauses of the present document and in each case, compliance enables the ancillary equipment to be used with different radio equipment.
