1 Test Description

1.1 General/Overview
With initial sample testing, the Telegärtner Labs evaluate whether an infrastructurecomponent complies with national or international standards. With this sort of testing,selected samples are usually tested before the production of a series starts.

To ensure superior product quality, the Telegärtner Labs test passive components anddevices according to the most demanding national and international standards.
With Telegärtner’s Real-time Re-embedded testing procedure,
components and devices are tested according to the demanding
category 6A specifications. However, these specifications are not
relevant for all kinds of components. Depending on the very type,they have to be tested as individual components or as part of anassembly or a link.
Telegärtner is one of the very few companies who are able to test
components without the need for baluns to be used as an adapter
between the tester and the device to be tested. Telegärtner’s direct
fixture test procedure allows the fixture of the device under test tobe connected directly to the tester. This leads to more precise andmore reliable test results than usual test procedures.

For a detailed description of the component to be tested, please refer to chapter 1.2 Device
under Test (DUT).
The standards against the component is tested are listed in chapter 1.4 Applicable Standards.

1.3 Parameters to be testedThe following parameters of the DUT were tested:a) Return Loss
When an electrical signal travels along a link, any disturbances that might occur (e.g.
transition from a cable to a connector, transition from a connector to a module (“plug tojack”)) or any changes whatsoever cause a part of the signal to be reflected at the very point
the disturbance appears. The return loss indicates how much of the signal is being reflected.
As the return loss is by convention expressed as a logarithmic ratio of the signal power
returned to the incident signal power, a high return loss value is desirable and means that
only very few power is reflected.

b) NEXTThe acronym NEXT stands for “near end crosstalk attenuation”. Crosstalk means that thesignal travelling along one pair of a cable can be detected on an adjacent pair as well, whichis unwanted. NEXT is the attenuation (“suppression”) of the unwanted crosstalk at the nearend of a link. Similar to the return loss, a high dB value of NEXT is desirable because it
indicates that only very little of signal energy leaks into adjacent signal lines.

1.4 Applicable Standards
The device was tested according to the following standard:

2 Test Setup

2.1 General/Overview
The test was conducted in the Telegärtner Lab in Steinenbronn, Germany, as described inchapter 2.2 Test Setup, in a standard lab environment.

2.2 Test Setup
The device under test was connected to the test fixture.
The fixture was connected to an 8-port network analyzer using coaxial cables.
Baluns as adaptors were NOT used.

2.3 Tester
8-port network vector analyzer Rohde & Schwarz ZVT 8with calibration unit ZV-Z58, 300 kHz to 8 GHz.

2.4 Test Adapter
Telegärtner Re-Embedded fixture.
The advanced probe fixture design eliminates the need for baluns, leading to more accurate
test results.

The results of the pairs 4578 seem to be below the limits in the frequency range of 10 to20 MHz. However, this is a snapshot of an instantaneous signal trace frozen in time. Very low
signal levels below 65 dB are susceptible to small changes in the physical arrangement ofDUT and fixture. In this sense the limit line is not really violated. Furthermore, in this very
low frequency range there is ample headroom to the channel specifications.
Please note that most critical is NEXT above 250 MHz.
