1、Op. ITU-R 2-2 OPINION ITU-R 2-2 1 COOPERATION WITH THE INTERNATIONAL SPECIAL COMMITTEE ON RADIO INTERFERENCE (Questions 4/1, lO/l, 35/1,46/1, 57/1 and 81/1) (1963-1978-1990) The CCIR, CONSIDERING (a) desirable; that cooperation between the International Special Committee on Radio Interference (CISPR

2、), and the CCIR is (6) that cooperation between the CISPR and the CCIR has been of value; (e) particular, safety services; that it is desirable to interchange information concerning the protection of radiocommunication services, in (4 measurement and radiation limits adopted, that to facilitate the

3、exchange of such information it is desirable to reach agreement on the methods of IS UNANIMOUSLY OF THE OPINION that the CISPR should be invited 1. radiation limits; to advise the CCIR of any proposals they have under consideration for the methods of measurements and 2. to take into account all the

4、studies done by the CCIR relevant for the work of CISPR, 3. to continue cooperation with the CCIR on the following subjects: 3.1 study of methods for the measurement of radio interference and, having due regard to the frequency bands used by safety services, of procedures (in some cases issued by th

5、e International Electrotechnical Commission), for limiting undesirable radiations produced by: electrical apparatus and installations (Question 4/1, Study Programme 4A/1); all types of receivers (Recommendation 239; Question lO/l; Publication 106 of the International Electrotechnical Commission); 3.

6、2 determination of the maximum interference level tolerable in complete systems (Question 4/1); 3.3 identification of sources of interference with radio reception (Question 35/1); 3.4 study of the usable sensitivity of receivers in the presence of quasi-impulsive interference (Question 57/1); 3.5 st

7、udy the relationships between various parameters of man-made noise, in particular between the quasi-peak voltage, the mean noise power, and the amplitude and time distributions of the received noise (Questions 46/1, 29/6 and Study Programmes 46A/1,29C/6). Note - The Director of the CCIR is invited to transmit this Opinion to the CISPR with Report 1104.
