  • REGRESSION TEST AND DEVELOPER SUPPORT
  • CONTROL AND VISUALIZATION BY CLIENT
  • CONTINUOUS SUPPORT AND FURTHER DEVELOPMENT

TSEP Kerberos is a hardware and software solution for verifying the LXI functionality of measuring instruments. The current TSEP Kerberos version 1.12 delivers identical results as the current LXI Conformance test suite of the LXI consortium, however TSEP Kerberos offers a holistic solution from hardware, software and client for the execution and evaluation of LXI Conformance tests.

The TSEP Kerberos hardware contains an independent computer core and various hardware components to perform the individual tests, such as hardware for the automatic network interruptions (plug on/off of the network connector), the IEEE 1588 tests and hardware for detecting the transmission speeds. To ensure that all necessary network protocols and settings for IPv4 and IPv6 can be set, all necessary network settings are set via an integrated router (Open-WRT). This means that the measuring instrument to be examined is integrated in its own separate network and is completely isolated from disturbing external influences. All test-specific data is stored and signed directly on the hardware. This signing of the test-relevant data ensures that only data sets generated by the test suite can be recognized as such and processed further. Since all data is generated directly on the TSEP Kerberos hardware, it is not possible to manipulate the test results.

The TSEP Kerberos software is designed as client/server software and is available in different variants. The underlying TSEP Kerberos "Base" version runs on the TSEP Kerberos hardware and is responsible for executing the tests and generating the test report. Additional functionalities are included in the variant TSEP-Kerberos "Regression Test". For this purpose, client software is provided that can be used in batch or script mode, allowing automated regression testing. Thus this solution can be easily integrated into automated tests. Improved troubleshooting support is implemented in the TSEP-Kerberos "Ultimate" version.

The TSEP Kerberos Client is used to define the Device under Test (DUT), to define the test parameters, to select the tests and finally to control the process. Furthermore, the client visualizes a detailed procedure in the form of test steps and their documentation. Since the documentation of the standard is included with each rule and the individual test steps are also described in detail, the user is clearly visualized at all times which TSEP Kerberos test sequences are necessary for a specific test. The client software is available for Windows (Windows 7, 8 and 10) and Linux (Ubuntu).

TSEP has been working on the LXI instrument standard for more than 10 years and is also an active member of the LXI consortium. In addition, TSEP 2014 has also been certified as an LXI test house and conducts LXI certification tests for various LXI member companies. As current advancements for TSEP Kerberos the topics "LXI Security" and the self-certification of devices by LXI members stand in the foreground. TSEP is actively involved in both topics and participates in the various LXI working groups. Thus TSEP ensures that the future extensions of the LXI standard are supported by the TSEP Kerberos Test Suite. Customers who have a TSEP Kerberos support contract can download these enhancements and extensions directly from the TSEP SFTP server for free and use them on their devices!
