Transfer Impedance or Shielding Effectiveness Test
The tests are intended to characterise the quality of a shielding system.
One of the tests shall be performed.
The transfer impedance is preferred, shielding effectiveness is an optional test.
A single port assemblies shall be tested to represent connector family.
Only fully shielded connectors shall be tested .
6.4.1
Transfer impedance is defined as the quotient of the longitudinal voltage in the outer
system to the current in the inner system.

A triaxial test set-up shall be used in accordance with IEC 61196.
All terminating resistors shall be 50 ohm
Maximum value is 1.3 ohm (to be verified)
6.4.2. Shielding System Effectiveness - The specification requirement shall be satisfied when
evaluated in accordance with FCI Test Specification BUS-03-107 and the following details:
The following requirements are applicable to products with full shield.
Every port should have at least three grounding pegs.
In lieu of grounding pegs, a copper tape can be used.
No shield effectiveness test required for products with partial shield.
