Cable Test Service

Test reports

eVision Systems tests USB, HDMI & DVI cables for compliance with the applicable cable specification. Our tests are subject to strict framework conditions and are implemented with professional tools. For each tested cable you will receive a comprehensive test report. You can get an example of a test report result in the link below.

Why should cables be tested?

Although the production costs of the cables are becoming increasingly expensive due to constantly rising complexity in manufacturing, the selling price of the cables increases only minimally.  This is why the cable manufacturers are all based in low-wage countries. Due to the cost pressure, quality assurance measures are mostly missing and outgoing tests are only carried out to a very limited extent.  Buyers and intermediaries are advised to take their own measures to verify the quality and functionality of the cables in order to prevent potential problems from arising in the first place. 

Faulty cables, especially of the increasingly complex USB cable types, can lead to transmission errors and even dangers such as irreparable device damage or even device fires. Stress on support, expensive recalls and thus damage to the brand and reputation are consequences that can be avoided by a cable test. Especially with HDMI cables, which are expensive to manufacture, and USB cables, which are becoming increasingly complex, appropriate validation of specification parameters is important. An incoming inspection by sampling is usually sufficient. 

We test contact continuity, IR drop / DCR, e-marker data and signal integrity of the cables and provide the data in a single test report. Our testing has a signal integrity test that provides data and output of signals of various speeds with a coupling eye diagram of up to 12.8 Gbps. This provides companies with a much simpler and cost-effective way to verify the transmission quality of a cable. In addition, we are able to customize the test variables based on the applicable cable specifications. For our tests we use the cable tester ACTv2, which was developed in close cooperation with the USB Implementers Forum Inc. as well as Apple Inc.


The development of the USB specification

To explain the increasing need for cable testing, consider the evolution of the USB specification, which today allows power output of up to 100 watts. In the past, USB cables were simpler to design and manufacture, but the development of the USB bus is very dynamic, which means that USB cables are subject to increasingly complex specifications. Due to the high currents and transmission speeds that a USB cable must support starting with the USB 3.0 specification, it is a more difficult task for manufacturing to meet the high specification requirements and stay within tolerances. However, for the first time, even small percentage deviations from specification in cables or power supplies lead to problems, damage or, in the worst case, injury due to the many times higher potential power output. In the meantime, there have been numerous cases of burned-out or blown Type-C charging sockets caused by untested power supplies or cables whose resistors were incorrectly dimensioned and thus emitted too much power.

USB performance specifications

USB 1.0 / 1.15 V0.1 A0.5 W
USB 2.05 V0.5 A2.5 W
USB 3.0/3.15 V0.9-1.5 A7.5 W
USB BC 1.25 V1.5 A7.5 W
USB Typ C5 V3 A 15 W
USB PD5 V / 12 V / 20 V5 A100 W


For these reasons, testing and ensuring that defective cables do not cause damage to this requirement has become a necessity. In order to guarantee sufficient quality and safety of the cables to the end users, the best solution for suppliers and companies that purchase untested cables is to carry out sufficient cable testing themselves or have it carried out by third parties. To be able to meet the high diverging requirements at the same or lower price, there is a central starting point through the given test parameters, which can be checked with our cable tests.
