Radio Frequency Engineering for Industry, Research and Testing – precise, accredited, globally recognized
Seibersdorf Laboratories’ radio frequency engineering (RF) combines scientific precision with practice-oriented solutions. We support our customers in developing, validating and optimizing RF measurement processes – from antenna calibration and test site validation through to high-precision reference antennas and measurement systems.
We understand the challenges faced by OEMs, test laboratories, universities and technology developers, and we provide solutions tailored specifically to technical, regulatory and commercial requirements.
We calibrate antennas, field probes and RF test equipment over a wide frequency range – from low-frequency applications up to the gigahertz range, depending on the measurement method and the respective measurement environment.
Our calibrations are performed in accordance with ISO/IEC 17025 using traceable reference standards and established measurement methods. The selection of the appropriate method is always application-specific to ensure an optimal combination of measurement accuracy, reproducibility and normative conformity.
Measurement uncertainty is determined in accordance with the GUM and documented transparently in the calibration certificate. This provides our customers not only with measured values, but with a robust basis for conformity assessments, quality assurance and audit processes.
In addition, in recent years we have carried out scientific investigations into calibration methods, published the results and actively contributed them to European and international standards.
Seibersdorf Laboratories supports operators of anechoic chambers, open area test sites, reverberation chambers as well as TEM and GTEM cells in verifying and assessing the electromagnetic properties of their measurement environments. The goal is to ensure that the respective environment meets the prerequisites required for reliable emission and immunity measurements.
Our site validation services are aligned with the applicable international standards and take into account site-specific parameters such as field uniformity and attenuation and reflection characteristics. The tests are performed with traceably calibrated reference antennas and measurement systems and are evaluated systematically.
The result is detailed and traceable documentation of the test site status. It is suitable both for internal quality assurance and for external audits and certification procedures.
Seibersdorf Laboratories’ RF products and measurement systems are used for demanding tasks such as antenna characterization, calibration and test site validation. Our reference antennas, reference transmitters and calibration systems are in use worldwide in accredited laboratories, industrial test environments and research institutions.
Originally, these systems were developed for in-house use in order to perform specific calibration and validation tasks with high accuracy and efficiency. Based on this practical application, they were consistently further developed, optimized and brought to market maturity. Today, they are also available to external customers as proven, practice-tested solutions.
All products are metrologically characterized in our own laboratory and calibrated with traceability. This makes them suitable both for routine quality assurance and for precise comparison and reference measurements.
Systems such as PLA, POD, PCD, RefRad™ and CalStan™ stand for scientific accuracy, robust design and high long-term stability. The combination of in-house research, practical application experience and active participation in standardization ensures that our products deliver reproducible and robust measurement results over the long term
Seibersdorf Laboratories’ radio frequency engineering goes beyond standardized testing and calibration services. Our research and technical consulting supports companies, test laboratories, research institutions and international standardization in analyzing complex RF questions, optimizing measurement processes and metrologically safeguarding new technologies. We combine scientific methodology with practical application experience from industrial and regulatory projects.
Our experts support customers in planning and assessing measurement setups, interpreting normative requirements, and analyzing measurement uncertainties and deviations. Depending on the task and project phase, our services range from targeted consulting to long-term technical support in development or research projects. The results often feed into optimized measurement strategies, robust decision-making bases or new test methods.
A particular focus is on supporting non-standardized or novel measurement tasks, for example in connection with new frequency bands, innovative antenna concepts or complex electromagnetic environments. Through our active participation in national and international standardization committees, we can take current normative developments into account early and incorporate them into our consulting.
We support companies and research institutions with special projects, uncertainty analyses, measurement setup planning and interpretation of normative requirements.
Seibersdorf Laboratories’ research and consulting services thus create a bridge between theory, standardization and practical implementation – helping customers minimize technical risks, shorten development times and sustainably improve the quality of their RF measurements.
Within the scope of research and consulting, we support, among other things, with:
These services are adapted to the respective technical, regulatory and organizational framework conditions.
Our validations and calibrations are accredited in accordance with ISO/IEC 17025 and are recognized worldwide in all EA and ILAC member countries.
The activities of our business unit are based on many years of scientific research. For our products, the research results form the basis for continuous further development.
Accreditation Confirmation
Scope of Accreditation
We support companies and organizations whose products and technologies are based on reliable radio communication or electromagnetic properties. These include:
We provide specific services and problem-solving, tailored to their use cases and to technical and normative requirements.
Accredited test laboratories need absolute reliability and traceability in their measurement processes. Any deviation can delay certifications, complicate audits or call measurement decisions into question.
We help laboratories keep their measurement competence under control – for the long term. Whether test site, antenna or instrument: we regularly check that everything measures as it should. What matters to us is not only the result, but also the path to it: clearly documented procedures, transparent measurement uncertainty and alignment with international standards. From individual calibrations to long-term stabilization of entire measurement processes: we support you exactly where you need it.
Through this cooperation, test laboratories obtain a reliable basis for audits, assessments and proficiency testing, and can offer their services with a high level of technical and formal confidence.
Benefits for test laboratories
Typical use cases
Manufacturers and OEMs need RF measurement data that not only “roughly fits”, but is reproducible under real conditions – across development cycles, sites and test benches. At the same time, requirements are increasing due to international standards and global markets, for example in telecommunications, automotive, medical technology or industrial automation.
Seibersdorf Laboratories supports manufacturers of antennas, sensors and RF modules with high-precision metrology and many years of experience from accredited calibration and validation tasks. Our measurements are traceable, standards-oriented and documented in a way that makes them suitable for internal decisions as well as external testing and regulatory requirements.
Our services accompany the entire product lifecycle: from development and prototype phases through series preparation to ongoing quality assurance. We help identify measurement risks early, set up test configurations efficiently, and keep measurement processes stable over the long term.
Benefits for manufacturers
Typical tasks
Anechoic chambers, shielded rooms, antenna test sites and test equipment must be designed and integrated so that they meet the requirements of relevant standards and enable reproducible measurement results in later operation. Seibersdorf Laboratories supports suppliers of EMC test laboratories with independent RF expertise across the entire lifecycle of a test site.
Our services range from metrological assessment of newly built anechoic chambers and shielded rooms to verification of existing installations during ongoing operation. Both the electromagnetic properties of the infrastructure and the interaction of antennas, instruments and measurement environment are considered. Relevant parameters such as field uniformity, reflection behavior or suitability for defined test procedures are assessed and documented in a traceable manner.
Through this independent validation, suppliers and their customers obtain a well-founded basis for acceptance, optimization and further development of EMC test laboratories. At the same time, potential weaknesses can be identified early and costly rework avoided.
Research institutions need highly precise and traceable RF measurement data to convincingly substantiate scientific results. Whether in basic research, applied projects, bachelor’s, master’s and doctoral theses, or international consortia: the validity of experimental data is always central.
We support research projects in different phases – from planning the measurement setup and performing measurements through to interpreting the results. Our experience from applied research, standardization work and industrial projects is incorporated. The measurement data provided are suitable for publications, project reports and funding programs and create confidence in the quality of the underlying measurement methodology.
With decades of experience working with research projects, we understand the requirements of scientific groups – including the need for reproducible results, cleanly documented traceability of measurement quantities and transparent presentation of measurement uncertainty.
