Services > Measurement, Test Automation, Verification and Validation

Trust, but Verify. Verify, but also Validate.

Every design needs verification and validation. According to our experience, the time and costs spent on testing, debugging and reviewing roughly corresponds to the time and costs spent on the product design itself. By verification we check that our products meet a set of initial design specifications while the design validation is the standard part of our customers' acceptance and system tests.

Our experience covers definition of test strategies for all levels of verification and validation, starting from tests of design samples through board level tests up to functional tests and complex test systems. Furthermore, we can define stress tests, robustness tests and provide product testing according to external requirements.

Production testing is a part of our tasks. Our LabVIEW experts have designed several production testers which are able to control high-end complex measurement devices, do automatic or semi-automatic tests, interact with an operator, and also generate detailed reports.

Based on our design and testing experience we can support our customers in the following fields:

Test strategies

Are you not sure if your product fulfills all ETSI requirements? Not sure how to measure EMC, MAC parameters? Would you like to measure VSWR (voltage standing wave ratio) below 1.1? Not sure how to calculate measurement uncertainties, UGBs, and measurement errors?

-> We can help you with definitions or reviews of test strategies, methods or definitions of suitable measurement instruments.

Manual measurements

Is your development team too busy with core design tasks, so that you do not have time to handle your necessary manual test routines, measure all the specified points, and improve test coverage of your product? Are you under pressure to re-measure your prototype with the latest software release?

-> We can support you with our experience in all such activities, and additionaly, in measurement and creation of test reports.

Automated test systems

Would you like to lower costs of regress tests? Would you like to automate the tests done manually in design phase and to move them to the production line in the factory? Would you like to relieve your team from writing the test reports?

-> We know these topics. We have always tried to automate as many tasks as possible. Let us find together what we can do for you.

We have experience based on design of dozens of testers from simple test adapters to complex verification systems for the production.

On the basis of input requirements we can determine which parts should be designed in-house and which parts should be purchased as the standard components to meet the expected costs and time to market (TTM) requirements.

Here is the brief summary of our test team history:
