32、test procedures corresponding to those requirements by cross reference to (a) specific clause(s) in the present document or to (a) specific clause(s) in (a) specific referenced document(s); it qualifies each requirement to be either: - Unconditional: meaning that the requirement applies in all circu

34、ifies each test procedure to be either: - Essential: meaning that it is included with the Essential Radio Test Suite and therefore the requirement shall be demonstrated to be met in accordance with the referenced procedures; - Other: meaning that the test procedure is illustrative but other means of

35、 demonstrating compliance with the requirement are permitted.

39、and arrangements for radiated measurements B.1 Test sites B.1.1 Open air test sites The term “open air“ should be understood from an electromagnetic point of view. Such a test site may be really in open air or alternatively with walls and ceiling transparent to the radio waves at the frequencies con

Absolute or relative measurements may be performed on transmitters or on receivers; absolute measurements of field strength require a calibration of the test site. Abo

For measurements at frequencies below 1 GHz, a measurement distance appropriate to the frequency shall be used. For frequencies above 1 GHz, any suitable measuring d

The height of the equipment or of the substitution antenna shall be 1,5 m; the height of the test antenna (transmit or receive) shall vary between 1 m and 4 m. Sufficient precautions sh

44、e site according to CISPR 16 2; all cables shall be as short as possible; as much of the cables as possible shall be on the ground plane or preferably below; and the low impedance cables shall be screened.
