Triaxial test set // EC VERIFIED

Transfer impedance
Screening attenuation

EC (European Cabling) Group of DELTA has during the last years supplied many customers with test fixtures for measurement of transfer impedance. The use of the fixture has now been extended to comprise screening attenuation measurement according to the triaxial method.
The following table gives an overview of test methods and required coupling lengths.

Measurement	Frequency range	Test method	Standard	Coupling length
Transfer impedance	up to 30 MHz	Triaxial	EN 50289-1-6	1 m
Transfer impedance	up to 100 MHz	Triaxial	EN 50289-1-6	0.3 m
Screening attenuation	100 MHz - 3 GHz	Triaxial	EN 50289-1-6	3 m
Screening attenuation	200 MHz - 3 GHz	Triaxial	EN 50289-1-6	2 m
Screening attenuation	300 MHz - 3 GHz	Triaxial	EN 50289-1-6	1 m



1 m test fixture.	Diaphrams for different sizes of cables (3 mm to 25 mm in steps of 2 mm).	Complete set of fittings for measurements length from 0.3 m to 3 m.

Besides the above triaxial test-set for measurement of LAN data cables, we are also able to deliver a test-set for measurement of connecting hardware.
