General 1 Scope This standard specifies requirements for radio frequency and coaxial cable assemblies operating in the transverse electromagnetic mode (TEM). 2 Object This standard establishes uniform requirements for testing the electrical, mechanical and clim
32、atic properties of r.f. and coaxial cable assemblies composed of cables and connectors. NOTE 1The design of the cables and connectors used should preferably conform to the applicable parts of IEC 96 and IEC 169 respectively. NOTE 2This specification does not include tests which are normally performe
33、d on the cables and connectors separately. These tests are described in IEC 96-1 and IEC 169-1 respectively. 3 Related documents IEC 68:, Environmental testing.

35、a combination of a cable and connectors with specified performance, used as a single unit 4.2 insertion loss the loss introduced by inserting a cable assembly into a system in this standard it is the ratio, expressed in decibels, of the power (P1) delivered to a load connected directly to a source a
36、nd the power (P2) delivered to a load when the cable assembly is inserted between the source and the load Insertion loss = 10 log 4.3 reflection factor the ratio of the complex wave amplitude of the reflected wave to the complex wave amplitude of the incident wave at a port or transverse cross secti
37、on of a transmission line 4.4 electrical length the equivalent free-space length of the cable assembly 4.5 electrical length difference the difference in electrical length between cable assemblies 4.6 phase difference the difference in phase between a TEM wave which has traversed the cable assembly,
38、 and an identical wave which has traversed another cable assembly 4.7 propagation time the time taken for the propagation of a TEM wave between the reference planes of the two connectors 4.8 minimum static bending radius the radius used in climatic tests. It is the minimum permissible radius for fix
39、ed installation of the cable 4.9 dynamic bending radius the bending radius for the insertion loss stability, stability of electrical length and flexing endurance tests it is the minimum bending radius for flexed cable assemblies NOTEIn practice this implies conformity with the specification for a de
40、fined number of flexings. 4.10 Screening effectiveness 4.10.1 transfer impedance the quotient of the induced voltage on the inside of the cable assembly and the inducing current outside the assembly. In practice this is between defined points on connectors mated to the connectors of the cable assemb
41、ly 4.10.2 screening attenuation screening attenuation of the cable assembly is the ratio of the signal power inside the cable assembly to the total power that radiates outside the cable assembly P1 P2 - Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 11 09:08:36 GMT+00:00 2006, Uncontrolled Copy

NOTE 2Power ratin
43、g is dependent on mounting details, ambient temperature, air pressure and circulation. It is normally specified at an ambient temperature of 40 C. 5 Design and manufacturing requirements 5.1 Cable design and construction Cables conforming to IEC 96-2 or cables designed in accordance with the general
44、 guidelines of IEC 96-0 shall be specified wherever possible. Where cable designs deviating from IEC 96 are required, these cables shall comply with the requirements of the detail specification. 5.2 Connector design and construction Connector types conforming to the relevant part of IEC 169 shall be
45、 specified wherever possible. Where a special connector design is required, the interface shall conform to the relevant part of IEC 169, where available and the connector construction shall comply with the requirements of the detail specification. 5.3 Outline and interface dimensions a) Outline dime
46、nsions shall be in accordance with the detail specification. b) Interface dimensions shall be in accordance with the detail specification. 6 Workmanship, marking and packaging 6.1 Workmanship There shall be no observable defects in the cable assembly; it shall be clean and in good condition. 6.2 Mar
47、king Marking shall be legible and in accordance with the detail specification; it shall identify the manufacturer of the cable assembly. 6.3 End caps Unless otherwise specified in the detail specification, disposable end caps of suitable material for transport and storage shall be fitted to the conn
48、ectors to protect at least each interface from damage and dirt. 6.4 Packaging and labelling Packaging and labelling shall be in accordance with the detail specification, unless otherwise specified. 7 Artificial ageing Artificial ageing may be used to improve the stability of phase attenuation and ex
49、pansion with temperature. This process normally consists of submitting the complete cable assembly to a number of temperature cycles. Unless otherwise specified in the detail specification, submitting the complete cable assembly to artificial ageing is optional at the discretion of the supplier. Section 2.
