Description: We test each feature of the product against its original design specification, using pre-defined test cases that address both typical and extreme conditions.
Description: We apply procedures such as temperature cycling, humidity and vibration testing, along with Ingress Protection (IP) testing, to see how the product will behave in the environments it will experience in real life.
Description: We carry out pre-compliance testing to CISPR and IEC standards to assess emissions and immunity issues. This means problems are identified before the product is submitted to an accredited testing lab.
Description: We perform both unit and integration testing on embedded firmware and applications, checking code coverage and ensuring the product reacts correctly to expected conditions and failure points.
Description: We design custom ATE and functional test jigs to automatically check every single unit on a production line. This can include checking both firmware and communication protocols.
Description: We generate the required technical documents and test reports for the product's compliance submission, for instance for CE, FCC, BIS and other certifications. We liaise with an accredited certification lab throughout this process.
Description: We examine failed or returned units to identify the fundamental reason for failure. This could be design, component or process-related, and prevents a problem from being classified and treated as an isolated occurrence.
Most vendors run a generic checklist without understanding the product. We treat testing as design-informed engineering — functional, environmental, and EMI/EMC as one connected effort, from Thane, Maharashtra.
Tests that are designed based on actual potential issues with the product.
Test scenarios are aligned with real industrial operating conditions rather than generic profiles.
Pre-compliance skills that come from experience working with CISPR and IEC standards.
From test case generation to certification documentation – all under one roof.
When off-the-shelf solutions are not suitable, we develop custom test equipment.
Not just fixing the issue but solving the root cause of failure.
From a simple pre-compliance scan to full-fledged ATE in production.
Complete documentation remains your intellectual property.
Choose the testing and quality support model that fits your product stage, test requirements, and validation goals.
A clearly scoped testing program with defined test requirements, procedures, and deliverables.
A dedicated engineering team supporting your product testing and quality activities throughout development.
Extend your existing engineering team with testing and quality specialists when additional support is needed.
Continuous testing and quality support across product development, validation, production, and improvements.
Representative examples of the kind of testing and quality work we take on.
Challenge: One of our clients' industrial controllers failed emissions testing at a certified lab, delaying their path to certification. We ran a pre-compliance EMI scan on the device's PCB and identified a board layout issue that was the root cause of over-spec'd conducted emissions. Result: We re-designed the PCB layout and they successfully completed certification at the lab on their next attempt - saving them a second booking of their expensive certification lab.
Challenge: A client needed 100% testing coverage on a new HART transmitter production line, without slowing down production. We developed a fully automated ATE fixture that automatically exercises their device on each unit and performs an automated calibration, while also ensuring a HART command test to check for overall functionality. Result: Every unit is automatically tested to a consistent pass/fail standard across multiple shifts, with a drastic reduction in communication-related field returns.
Challenge: One of our clients needed to ensure their outdoor field device was correctly rated for IP65 ingress protection before starting production on hundreds of units. We ran ingress protection, temperature cycling, and vibration testing to the design's specification. Result: The enclosure successfully maintained its IP65 rating, with only minor seal design changes needed, increasing confidence for the large production run.
Testing does not end with development. We help establish practical inspection and validation processes that support consistent quality during manufacturing.
Define test procedures, acceptance criteria, test coverage, and validation requirements based on product specifications.
Develop practical testing fixtures and setups for repeatable functional and production-level testing.
Verify product functions, interfaces, communication, and performance against defined technical requirements.
Support manufacturing teams with inspection procedures, testing workflows, failure analysis, and quality checks.
Establish validation and quality processes that help identify defects early and maintain product consistency during production.
Testing & Quality Engineering verifies that a product performs according to its design intent, endure its operational environment, and does not adversely affect, or is not adversely affected by, nearby electronics. Testing & Quality Engineering ranges from functional testing of the design through environmental & reliability testing to EMI/EMC pre-compliance to the necessary documentation to confirm it all was performed successfully. A product should not be considered ready simply because it operates correctly on an engineering bench, and then break due to the temperature fluctuations, vibrations, or electromagnetic spectrum it will encounter once fielded, and so tests must be configured based on the product's actual expected operational conditions, not just some general pass/fail matrix.
Questions we hear on every testing and quality scoping call — answered directly, without the brochure language.
Functional, environmental & reliability, EMI/EMC pre-compliance, firmware & software testing, and the development of automated test equipment and root cause failure analysis.
Yes, we are able to perform EMI/EMC pre-compliance testing against standards such as CISPR and IEC to identify and diagnose any emission and immunity problems prior to a product's submission to an accredited certification laboratory.
Yes, we design Automated Test Equipment (ATE) and functional test jigs to verify every unit produced to specification (this can include firmware and communications protocol checks where necessary) as it comes off the production line.
Yes, we perform root cause analysis and Failure Analysis on returned or failed product units where the same defect is encountered repeatedly. The goal of this analysis is to get to the cause of the issue rather than simply treat each failure as a discrete incident.
We conduct and measure temperature cycling, humidity, vibration, and Ingress Protection (IP) tests on a given product to ensure that it will function in its intended environment prior to shipping.
Yes, Rhosigma has experience of supplying technical data sheets, test reports and all relevant technical documentation necessary for the submission of CE, FCC, BIS and other relevant regulatory certifications, supporting all certified laboratories' requirements.
