Test Systems

Bespoke test solutions are our speciality. We have the experience and capabilities to design and build any type of test equipment from fully automatic test systems, test sytem hardware and their operating software down to simple break out boxes.

Our engineering team contains over 50 experienced test engineering specialists with all of the skills and tools required to professionally manage a wide variety of test development projects. Our engineering processes ensure that each project follows a standard project management and system engineering approach. We conduct regular reviews with fixed tollgates from the requirement capture and concept design phase, through critical design, into manufacture and test and on to final delivery. We can also deliver test system hardware and build-to-print services for test equipment.

To enable OES to offer a complete test system design and build service we have invested in the best 3D mechanical, electrical and electronic design tools and the best people. In addition to this, our service offers all of the disciplines and controls expected in the industry fields in which we operate.

Manufacturing floor

Our flexible manufacturing area allows us to dedicate space and facilities to different projects as required. We can change to meet the different needs of our various customers. We can set-up a manufacturing cell for small production runs of test cables or boxes. Or we can re-configure to be able to integrate and commission large test systems before shipment.


Our solutions are generally based on accepted test methodologies and industry standard hardware. We try to use off the shelf solutions where possible but we are adept at designing bespoke elements when required.

For example:

beds of nails

test jigs and fixtures

specialist interfacing electronics

At OES, we regularly build test instrumentation into our systems, such as:



Signal Generators

PXI racks

We package our test solutions in bespoke enclosures as well as standard 19 inch racks. We use PCs, PLCs and microcontrollers in our control solutions, depending on the requirements of each project.


Our software solutions are similarly based on industry standard methods and tools. We have a dedicated Software Engineering team, with controlled processes and development methods. This aligns with our company strategy of being able to provide turn-key solutions for large test systems. All of our software developments follow a standard V model approach and are auditable to the ISO/IEC12207 standard.

Our philosophy

Our customers come back to us because we care. At OES, we apply rigorous management disciplines to all of our projects and communicate openly with all of our customers. In addition, we provide regular weekly updates by default, and we don’t try to hide anything.

We may not be the cheapest test solution provider on the market, but we are trying hard to be the best.

We believe that trust is a key enabling factor in the relationships we develop with our customers.
