EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 50289-1-2 testing. This section 50289-1 of EN 2 details test methods for determining the DC resistance properties of conductors of cables used in analog and digital communication systems. These properties are defined by conductor resistance, loop resistance, and resistance imbalance. It should be read in conjunction with EN 50289 section 1-1, which contains the essential provisions for its application.
Resistance shall be measured by equipment capable of measuring accurately within ± 0,5% of the values to be determined.
Both ends of the test specimen must be connected to the terminals of the meter for evaluation of conductor resistance and resistance imbalance. To determine the value of the loop resistance, each pair/side of a quad or inner/outer conductor must be measured short-circuited from one end to the other. Alternatively, the loop resistance can be determined by adding the two separate conductor values.
Measurements will be taken using a mixed-mode test setup, often referred to as an unbalanced, modal decomposition, or balunless setup. This allows measurements of balanced devices without using an RF balun in the signal path. With such a test setup, all balanced and unbalanced parameters can be measured over the full frequency range.
The test procedures described here require the use of a vector network analyzer or similar test equipment. The analyzer will be capable of full 4-port calibration and will be capable of isolation calibrations. The analyzer should at least cover the entire frequency range of the cable or wiring harness under test.
