16、ONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 21-1: RF resistance tests Test 21a: RF shunt resistance 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of technical committee 48. It may also be used
17、for similar devices when specified in a detail specification. The object of this standard is to detail a standard test method to determine the value of RF shunt resistance which degrades the quality factor of an L/C circuit when a connector is connected in parallel. This value is expressed in terms
18、of a parallel damping resistance. 2 Preparation of the specimen The specimen shall be prepared and mounted according to the detail specification. 3 Test method The R.F. shunt resistance shall be measured with suitable measuring equipment. The measuring points shall be specified in the detail specifi
19、cation. The measuring error shall not exceed 10 %. The test frequency shall be specified in the detail specification. The preferred frequencies are: 1 MHz, 10 MHz, 30 MHz and 100 MHz. 4 Requirements The value of RF shunt resistance shall be not less than the value specified in the detail specificati
20、on. 5 Details to be specified When this test is required by the detail specification, the following details shall be specified: a) preparation and mounting of the specimen; b) measuring points; c) measuring frequency; d) minimum value of RF shunt resistance; e) any deviation from the standard test m
