Who uses the lab

Three reasons companies come to our lab.

No in-house lab yet
You need to validate your ECU against LV124 or LV148 but don’t have the test infrastructure in place. Ship us your DUT — we run the complete norm and deliver a structured report.
Evaluating RTStand before investing
You want to see the system in action with your own ECU before committing to a purchase. Visit Ravensburg for a hands-on day — bring your DUT, define the tests you want to see, and assess the system’s capabilities directly.
New interface development
You are developing a new ECU interface — Automotive Ethernet, GMSL, or something custom — and need a partner to run proof-of-concept tests or validate integration before your own system is ready.
Lab services

Three types of engagement.

Whether you need a full certification run, a quick tryout, or help pushing a new interface, we work with you to define the right scope.

Service 01
Complete LV124 / LV148 test run
Full execution of all applicable LV124 or LV148 test cases for your ECU — including all power network tests, communication line checks, and climatic conditions where required. Delivered with a complete structured test report.

 

How it works: Ship your DUT to our lab in Ravensburg. We handle setup, execution, monitoring, and reporting. Full norm runs typically take several days to weeks depending on ECU complexity and the number of test variants. You do not need to be present — we keep you informed throughout.
Service 02
In-person assessment day
Visit our lab and run the specific tests you want to see with your own ECU, on the actual RTStand system. Designed for teams evaluating RTStand before a purchase decision or for engineers who want to see exactly how their DUT behaves under specific test conditions.

 

How it works: You visit Ravensburg, bring your DUT, and define the test cases you want to run. Our engineers set up and operate the system while you observe. Most teams make a full day of it — running a range of tests to get a complete picture of both the ECU’s behaviour and the system’s capabilities.
Service 03
Interface tryouts & proof of concept
Working on a new ECU interface — Automotive Ethernet 1000base-T1, GMSL, or something not yet in a standard test setup? We partner with you to test the integration in our lab before your own infrastructure exists.

 

How it works: We discuss your interface requirements, define the test scope together, and run controlled tryouts in our lab. This is also how several of our long-term customer relationships started — a proof-of-concept test that led to a system purchase.
How it works

Two ways to engage — your choice.

Both paths start with the same first step: a conversation about your ECU, your norms, and what you need from the test.

Option A

Visit in person

Best for: evaluation, specific test scenarios, seeing RTStand live

 

1. Contact us Tell us about your ECU, what tests you want to see, and a preferred date.
We’ll confirm feasibility and prepare the system.

 

2. Travel to Ravensburg Bring your DUT and any relevant documentation (pin lists, norm variants).
Ravensburg is well connected — A96/A98 motorway, direct trains from Munich, Stuttgart, Zurich.

 

3. Full assessment day Our engineers connect your ECU, configure the test cases you’ve defined, and run them while you observe.
Most teams run 6–8 hours of focused testing.

 

4. Results and next steps You leave with real data from your own ECU and a clear picture of what a full norm run would involve.
Option B

Ship your DUT

Best for: full norm runs, official validation, no travel needed

 

1. Contact us Share your ECU specs, pin list, applicable norms, and any OEM-specific variants.
We confirm scope, timeline, and a start date.

 

2. Ship your DUT to Ravensburg We confirm receipt and begin setup.
WKS Informatik GmbH, Ulmer Strasse 8, 88212 Ravensburg, Germany.

 

3. We run the full test Fully automated execution, days or weeks depending on scope. You are kept informed at key milestones — no need to be present.
Tests run unattended including nights and weekends.

 

4. Report and DUT return You receive a complete, structured test report. Your DUT is returned.
Report format can be discussed upfront.
Lab equipment

Built for the full LV124 / LV148 norm.

Our lab is equipped with the same RTStand systems we sell — which means every test we run for you is exactly what your own team would run in-house.

What customers say

From lab test to long-term partnership.

Many of our longest-running customer relationships started with a single lab engagement.

We have been using the RTStand LV124 / LV148 system from WKS Informatik for several years and are very satisfied with its high reliability and the fast, straightforward support. Regular maintenance and calibrations ensure that the system is always ready for use, and the personalized service significantly contributes to our satisfaction

SMR Automotive

The RTStand LV124 / LV148 system from WKS Informatik has not only increased our testing efficiency but also improved the workflow in our laboratory. Collaborating with WKS Informatik allowed us to implement custom adjustments, and we consistently benefit from prompt technical support. This efficiency and support have enabled us to effectively overcome the challenges of our dynamic development processes

Bühler Motor

The concept for automated testing of the LV124 prompted us to purchase a test system. The tests can now actually be performed and analyzed automatically. This saves time and resources. The support is also impeccable, and downtimes are minimized through a fast response time.

Leading automotive lighting supplier

We have reduced the overall testing time to a half compared to the previous manual testing and currently save 150.000 EUR for the LV124 testing of every several new software releases of our product

French automotive supplier

“One crucial advantage of your test system, besides timing and other benefits, is reproducibility! With a fully automated test run, there is no room for slight variations in the test runs anymore.”

Top 5 automotive supplier worldwide

This innovative modular concept, which gives us the opportunity to monitor a high number of pins in parallel, with a high resolution of up to 10us, as required in the LV124, allows us to make a deeper analysis of our products and especially find sporadic errors earlier in the development phase.
