3 Definitions
For the purposes of this European Standard, the definitions of EN 50290-1-2 and EN 50289-1-6 apply.
In this document connecting hardware is defined as a complete connecting device including compensating
or matching networks (if any), connectors and cable terminations.
4 Test method

4.1 Equipment

4.1.1 General
See EN 50289-1-6, subclause 9.2.1.1 and Figure 1 below.
The connecting hardware under test shall be terminated using the termination method and a cable type for
which it is constructed. If only one part of the connecting hardware is under test, a test head shall be used
to mate the part under test.

4.1.2 Balun requirements
For measurement of balanced connecting hardware, a means for generating balanced signals shall be
provided. If the generator is unbalanced, this may be performed by the use of a balun or 180° power
splitter.
The minimum requirements for this device are specified in Table 1.
The attenuation of the balun shall be kept as low as possible because it will limit the dynamic range of the
