Our Team

Our in-house process includes engineers, technicians, and machinists who take the test design from concept to reality. Test solutions are designed by a team of electrical & software engineers who focus in automated test, rather than a single test engineer.

What this means is that we can take your complex design, understand it, and optimize the test approach with minimal input from you. To summarize - if you don't have the time and/or expertise to figure out what or how to test, we've got you covered. Alternately, if you've provided specifications, we can professionally implement a test.


We've seen designs across the board, from military and industrial to consumer products, from satellite power distribution boards and aerospace servers to thermostats. Our testing experience allows us to plan and develop a thorough test, fast.

Lead Time

Subinitial's standard lead time is an industry-leading 3 months from receipt of the requirements & DUT.


A streamlined system yields efficiency, and a transparent process yields better results. We have honed in on our process in order to deliver full test solutions in tight timelines and on budget. Additionally, our internal processes allow us to incorporate best practices, and avoid test shortcomings, all captured through years of test developments.


Support is a critical long-term aspect for any test. Thorough documentation makes our tests easily maintainable, and Subinitial is always a phone call away.

Our Racks & Equipment

Built for Test

We design each system from the ground up to ensure we meet all system requirements. Where appropriate, we utilize designs from our library of existing tests to increase design speed and reduce cost. In this way, you benefit from our full test portfolio.

Our test racks utilize lessons learned from many rack designs, and are well thought through to aid in smooth operation, deployment, and support. Racks typically include things like advanced power management, a status/info display, and remote headless access.


Simple to deploy, we make our test setups self-contained with no external dependencies where possible. A hardened small form-factor PC is integrated in each test rack to run the tests. This ensures fixed-in-time versions of all test code, equipment firmware, drivers, and all other software, so you know the test is going to run exactly the same as it did the previous time it was used. This makes the test dependable.


Full-rack or half-rack test solutions are hard to store. Most of our delivered test setups are benchtop. We integrate miniaturized test equipment in each test rack where possible, so the test system doesn't balloon into a full rack. This allows the whole test setup to be easily pulled out of storage and set up on a bench, or sent to your contract manufacturer only for the duration of your manufacturing run.

Our Software

Software controls the test and the drives the operator experience. We make the test code clear and maintainable, and our software streamlines the operator interface for maximum throughput.


Each test comes equipped with the TestCenter test executive. See the TestCenter GUI page for details.


Our tests are written in Python. This popular, open-source, license-free language allows for comprehensive test control and absolute flexibility. Check out our Python Platform page for more details.


Good documentation is an important part of maintaining any test setup. Test procedure PDF's, test data reports, and source code always match due to our proprietary source code documentation system. Thorough code comments allow revision-controlled test procedure document generation straight from the source code. These consistent documents aid in accurate quality assurance and ease of future test maintenance. Hardware documentation is also provided standard and, of course, all documentation is version controlled.
