Traceable verification techniques for electrical measurements developed in EMRP project feed into industry-level documentation

Traceable electrical measurements are essential for cutting-edge electronics that operate in the radio frequency, microwave and millimetre-wave areas. EMRP project Metrology for new electrical measurement quantities in high-frequency circuits (SIB62 HF Circuits) has developed the traceable electrical measurement verification techniques that were previously lacking. The project has also provided significant inputs to European and international industry-level documentation so that industry can benefit directly from the work.

The IEEE (Institute of Electrical and Electronics Engineers) has used outputs from the project to help establish two new international standards:

- IEEE Std 1785.2-2016, “IEEE Standard for Rectangular Metallic Waveguides and Their Interfaces for Frequencies of 110 GHz and Above – Part 2: Waveguide Interfaces”

- IEEE Std 1785.3-2016, “IEEE Recommended Practice for Rectangular Metallic Waveguides and Their Interfaces for Frequencies of 110 GHz and Above – Part 3: Recommendations for Performance and Uncertainty Specifications”

In addition, a draft has been produced for the revision of “EURAMET Guidelines on the Evaluation of Vector Network Analysers (VNA)”. Finally, the work on millimetre-wave and submillimetre-waves has been submitted as a new Calibration and Measurement Capability (CMC) to the BIPM.
