Fulda. TSN Systems GmbH is represented at this year's virtual TSN/A Conference. On 7th and 8th October, the TSN Systems team will present the latest news from the 2020/21 product portfolio on AVB, PTP and TSN for automotive and industrial applications. Interested parties will have the opportunity to meet the TSN specialists at their virtual booth during the fair and learn more about TSN Tools and TSN Box.
Many companies are aware of the fact, that the requirements for new generations of devices should be TSN-compliant or at least "TSN ready". Development steps are now being initiated in this area, but the challenges in daily development work are comprehensive: gPTP-compliant time synchronisation and nanosecond cyclical traffic are the decisive issues. The focus is on the complexity of time-sensitive Ethernet communication.
Since 2016, TSN Systems has been working on offering analysis equipment with TSN Tools and TSN Boxes, which can be used to visualise - and thus understand - even complex situations. In current releases, new functions are constantly being developed that come directly from the daily practice of customers in TSN Engineering and thus show sustainable solutions.
In the new release 2.6 of the TSN Tools a special innovation for network analysis is available: The new configurationless dashboard provides a comprehensive network overview of the status resp. all involved talkers, listeners, VLAN, priorities, gPTP master and many other parameters with the help of so-called chord diagrams. With this unique approach, even complex situations are easy to grasp. Customers thus reach the goal of a convergent network faster and substantiated. Time Matters.

Shanghai (China). At this year's Automotive Testing Expo China 2020 TSN Systems GmbH was represented by its exclusive partner Polelink. The latest innovations from the 2020/21 product portfolio were shown from 14th to 16th September. Interested parties had the opportunity to meet the TSN specialists at their booth during the fair to learn more about TSN Tools and TSN Box.
“Together, Rohde & Schwarz and TSN Systems provide a comprehensive test solution for engineers who need to perform precise timing measurements on in-vehicle networks with nanosecond accuracy for Layers 1-3. In the collaboration, Rohde & Schwarz provides a tailored oscilloscope solution based on the R&S RTO, while TSN Systems contributes TSN Box, a hardware interface to the network and TSN Tools, a measurement and analysis software.”
With radar, lidar and camera sensors present in automobiles, time sensitivity on networks becomes extremely important, as vast amounts of sensor data need to be transferred and processed within a few milliseconds. Test and measurement expert Rohde & Schwarz and time-sensitive networks specialist, TSN Systems have successfully cooperated on precise timing measurements for in-vehicle networks using automotive Ethernet 100BASE-T1.

Advanced driver assistance systems (ADAS) require high bandwidth and low latency communications. Automotive Ethernet is becoming the de-facto communication solution to handle these requirements by offering higher data rates as well as time-sensitive network capabilities.
Together, Rohde & Schwarz and TSN Systems provide a comprehensive test solution for engineers who need to perform precise timing measurements on in-vehicle networks with nanosecond accuracy for Layers 1-3. In the collaboration, Rohde & Schwarz provides a tailored oscilloscope solution based on the R&S RTO, while TSN Systems contributes TSN Box, a hardware interface to the network and TSN Tools, a measurement and analysis software.
The test setup monitors an automotive Ethernet 100BASE-T1 communication link consisting of TSN Box 3.0 acting as talker, listener and test access point (TAP) device. The TSN Box 3.0 TAP device provides information to a PC with TSN Tools based on Layers 2 and 3. The TAP introduced 2x PHY delay for 100BASE-T1 at around 1.5 μs ±10 ns. The R&S RTO oscilloscope was used along with the R&S RTx-K35 bus measurements statistics option to measure and verify this timing accuracy in the physical layer of the automotive Ethernet signal (Layer 1). The mean time delay was measured to be precisely 1.5 μs with a max deviation of ±10.2 ns. In addition, the Qbv traffic (IEEE802.1) was generated by the TSN Box 3.0 with 500 μs cycle time resulting in a jitter ranging from 8 to 20 ns, which was verified by both the TSN Tools and the R&S RTO.
The combination of TSN Tools and TSN Box provides a broad range of functions to address validation and testing for time sensitive automotive Ethernet. While TSN Tools is a PC based analysis software performing visualization and deeo detail analysis, TSN Box serves as a precise interface to the link. Based on its configuration, it can act as a generic TSN Talker/Listener device with nanosecond precision. The TAP can transparently synchronize itself to the gPTP master in the network. This allows very powerful applications that need correlation between payload time stamps and TAP time.
The R&S RTx-K35 software option for the R&S RTO oscilloscope enables high precision latency measurements, for example monitoring the communication between two devices for a long period, and provides statistics on error rates as well as frame timing on the packets. The R&S RT-ZF7 test fixture acts as the link in the middle and allows the full monitoring between the transmitter and receiver device in both directions using the oscilloscope.
In combination with the suitable decoding option, the 100BASE-T1 time data can be measured frame-to-frame, and engineers can get full bus error statistics such as frame error rate and rate of consecutive errors. Moreover, they can perform precise timing measurements for all automotive serial bus protocols such as automotive Ethernet, CAN, CAN-FD, LIN, I2C and more.
Dr. Nik Dimitrakopoulos, Automotive Market Segment Manager at Rohde & Schwarz comments, “Our product portfolio has a strong focus in the automotive industry. With the addition of the R&S RTx-K35 option to our oscilloscope family, precise time measurements using various automotive communication standards are possible. We are very proud to assist TSN Systems to validate their timing information for their TSN Box 3.0 devices.”
Juergen Scheuring, Managing Director at TSN Systems, says, “The advent of time sensitive communication in next generation EE-Architectures raises some serious challenges for the test and validation teams at OEM and Tier1. We are happy to cooperate with Rohde & Schwarz and to benefit from their class-leading products providing Layer 1 analysis and expert level knowledge on time sensitive networking.”

TSN Systems presents comprehensive test suite for audio AVB/TSN validation in infotainment.
German measuring technology specialist TSN Systems presents an extensive AVB analysis suite, enabling precise testing complex of AVB / TSN communication in infotainment applications with its TSN Box 3.0 and TSN Tools products. This allows typical project teams in IVI development to master these technologies without having in-depth special knowledge in time-sensitive communication.
On the way to a service-oriented architecture, many OEMs are currently opting to use Ethernet AVB in the IVI. This is sensible considering how time-sensitive Ethernet communication is a significant role player in in upcoming EE architectures.
With the introduction of AVB, essential technological challenges of time-sensitive communication can be mastered without initially having to serve safety-critical applications. In particular, nanosecond synchronization using gPTP places considerable demands on ECUs. The complex analysis of gPTP and, as a secondary step, audio quality requires special knowledge that is not usually available in project teams.
Basic topics of the TSN Systems solution are gPTP time synchronization, audio analysis for IEEE 1733 and IEEE 1722 as well as jitter analysis of the media clock. Even in-depth analyses such as jitter induction in the gPTP master and the media clock are possible with the TSN Box. All analyses – including in-depth audio analyses – can easily be mastered with TSN Tools without special existing knowledge; thus leading to an efficient development workflow.
The AVB audio suite will be presented for the first time at the Automotive Ethernet Congress on February 12-13 in Munich and is available immediately. Our TSN experts look forward to interesting discussions with you at our booth.
Together with our sales partners from Polelink, we showed our TSN Box and TSN Tools at the Automotive Testing Expo China 2019 in Shanghai (September 24th to 26th).
TSN Systems introduces several novelties for the analysis of TSN-based networks in the industrial and automotive sectors.
The TSN/A conference is the annual industry meeting of all industries interested in TSN based communication. Nowadays, there is emphasis on industrial automation and in-car communication in particular. TSN Systems is continually expanding its product portfolio to provide manageable measurement and validation solutions for users in both industries.
Profinet-over-TSN monitoring with TSN Box and TSN Tools:
Based on the Profinet-over-TSN specification V2.4, TSN Systems can already offer a monitoring and analysis tool based on TSN Tools and TSN Box to analyze networks. Especially in the early phases of planning and implementation, users are therewith enabled to clearly analyze the critical parameters of time synchronization (gPTP) and isochronous data exchange (IEEE 802.1Qbv, Qbu). It is naturally also possible to analyze all networks based on the use cases of the IEEE Working Group 60802.
Audio Toolbox for IEEE 1733/1722:
With AVB, audio over Ethernet has already been technically established for several years. Nevertheless, the development of IVI systems based on IEEE 1733 and IEEE 1722 presents OEM and TIER1 with considerable challenges during development and validation. TSN Systems will present a comprehensive toolbox for the validation and development of AVB talkers/listers and gPTP masters at TSN/A for the first time. Many audio-specific analyzers such as media clock jitter, presentation time budget and gPTP jitter sensitivity are included in the package.
TAP Device for Ethernet-over-HDBaseT in Automotive:
Furthermore, TSN Systems in cooperation with Valens demonstrates a TAP device for Ethernet-over-HDBaseT. TSN Box 3.0 has been enhanced with the HDBaseT interface option for TAP and Talker/Listener to validate special IVI solutions based on HDBaseT.
TSN Systems will present measurement technology for the validation and planning of service-oriented EE architectures at the Bordnetzkongress.
TSN Systems was once again able to give some impetus to the valuable discussions with planners of EE architectures at the recently concluded Bordnetzkongress. The way to dynamic networks and the use of services in communication - mostly based on SOME/IP - seems to be generally accepted. However, this also involves new approaches to planning and, above all, securing vehicle networks, which in the future will have to be secured generically (i.e. payload-independently). For the necessary guarantees, the TSN standard solutions are available as a modular system. To meet these challenges, TSN Systems offers a portfolio of hardware and software.
