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 using professional tools. You will receive a comprehensive test report for every cable tested. An example of a test report result can be found in the link below.

Why should cables be tested?

Although the production costs of the cables are becoming increasingly expensive due to the constantly increasing complexity of the production itself, the sales price of the cables remains the same.  That's why the cable manufacturing is consistently located in low-wage countries, especially China, where most cable manufacturers are not willing to test their cables for quality defects due to a lack of budget. 

Defective cables, especially HDMI cables and increasingly complex USB cable types, can lead to transmission errors and even hazards such as equipment catching fire or irreparable equipment damage. These risks lead to lawsuits, expensive recalls and thus damage to the brand and reputation of the supplier and manufacturer. In addition to reputation, this also has monetary implications, as enormous losses can be incurred.  However, these consequences and risks can be avoided through thorough cable testing. Cables that pass our rigorous testing result in fewer product returns, fewer support calls, and minimized product recalls. This leads to higher profit margins and customer satisfaction, which contribute to your company's reputation and brand. Especially with HDMI cables, which are expensive to manufacture, and USB cables, which are becoming increasingly complex, proper validation of test parameters is important. In most cases, a simple spot check is sufficient to ensure the quality of a cable batch. 

We check the continuity of the contacts, the IR drop / DCR, the E-marker data and the signal integrity of the cables and deliver the data in a single test report. Our exam has a signal integrity test which provides data and output of signals of various speeds with a coupling eye diagram of up to 12.8 Gbps. This gives companies a much easier and cheaper way to check the quality of a cable. In addition, we are able to customize our test variables, which are based on the USB specifications. For our tests we use the cable tester ACTv2, which was developed in close cooperation with the USB Implementers Forum Inc. and Apple Inc.

 
 
 

The evolution of the USB specification

In order to explain the increasing need for cable tests, the development of the USB specification, which nowadays enables a power output of up to 100 watts, has to be considered. USB cables used to be easier to construct 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 from specification USB 3.0 onwards, it is a more difficult task for production to meet the high specification requirements and to stay within the tolerances. However, for the first time, even small percentage deviations from the specification for cables or power supply units lead to problems, damage or, in the worst case, injuries due to the much higher possible power output. There have been numerous reports of burned-out or burned-out Type-C charging sockets, caused by untested power supplies or cables whose resistances were incorrectly dimensioned and thus gave too much power.
 
 
USB performance specifications
Specification Voltage Ampere Power
USB 1.0 / 1.1 5 V 0.1 A 0,5 W
USB 2.0 5 V 0.5 A 2.5 W
USB 3.0/3.1 5 V 0, 9-1.5 A 7.5 W
USB BC 1.2 5 V 1.5 A 7.5 W
USB Type C 5 V 3 A  15 W
USB PD 5 V / 12 V / 20 V 5 A 100 W

 

 
For these reasons, testing and ensuring that defective cables do not cause any major damage with this requirement has become a necessity. However, most cable manufacturers are not ready to test their cables for quality defects. In order to guarantee the end users the sufficient quality and safety of the cables, the best solution for suppliers and companies that purchase untested cables is even a sufficient one Carry out cable testing yourself or have it done by third parties. In order to be able to meet the high, divergent requirements at the same or a lower price, there is a central starting point through the specified test parameters, which can be checked with our tests.
