Another project meeting was held on 9-10 April 2025 in Silkeborg, Denmark, hosted by Trescal (part of the Danish national metrology system). All participants discussed the project progress in the last 9 months in a nice collaborative atmosphere and future outlooks were given.
Some recent highlights:
▶️ The comparison on the automatic measurement of RF power up to 18 GHz is almost finished. Two more comparisons to start soon, i.e. (i) comparison of power sensor calibration factor measurement using a VNA and (ii) high attenuation measurement comparison.
▶️ New antenna measurement setups established in particular institutes, namely the monopole antenna and loop antenna setups and Helmholtz coil calibration setup.
▶️ Extensive antenna measurement comparison is almost finished. In particular, following comparisons have been organised: (i) ECSM for monopole antennas, (ii) EMC antennas in the frequency range 30 MHz – 1 GHz and (iii) high-frequency calibration using a fully anechoic room / free space in the range 1 GHz – 40 GHz.
▶️ Several new electromagnetic field standards have been built in institutes without previous experience - Helmholtz coils, uTEM cell, pyramidal tapered cells, parallel-plate capacitor. This is an important step towards offering new calibration services in the future.
▶️ Comparison on electric and magnetic field intensity to start soon in order to validate new measurement setups.
So far the project meets its goals, i.e. better preparedness of European national metrology institutes for future measurement challenges and research collaboration across Europe.
The project meeting in M18 was held on 8-9 October 2024 in Gebze, TÜBİTAK UME, Türkiye. The progress of the project was summarized and many fruitful technical discussions took place. The meeting was followed by two technical workshops. The first workshop summarized experience achieved with practical realizations of electromagnetic field standards in particular institutes (i.e., parallel plate capacitor, pyramidal cell, uTEM cell, improvements of anechoic chamber measurements). The second workshop presented the code-selective method for measurement of electromagnetic field intensity of cellular standards (3G, 4G and insight into 5G).
Thanks TÜBİTAK UME for creating a nice working atmosphere and their hospitality.
RISE, CMI, SIQ and TÜBİTAK are going to perform a comparisons of three types of antenna calibration capabilities during 2024. Several different antennas will be used as transfer standards.
The comparisons will be undertaken as follows
(i) ECSM for monopole antennas
(ii) antennas in the frequency range 30 MHz – 1 GHz (RISE, TUBITAK)
(iii) High-frequency calibration using a fully anechoic room / free space in the range 1 GHz – 40 GHz
The comparison reports will be published after the comparison end and available in the project website.
TÜBİTAK is going to organise and evaluate a comparison on the automatic measurement of RF power up to 18 GHz. The comparison will be a ring style type. Other comparison participants include CMI, GUM, IMBiH, NSAI, SIQ, Trescal and Spark. The AutoRFPower software developed by project partner Middle East Technical University will be used in the comparison.
Project partner Middle East Technical University is going to deploy their AutoRFPower software developed together with Spark Calibration Laboratory and TUBITAK UME to project participants IMBiH, Trescal, NSAI, SIQ and CMI.
The software can make automatic RF power measurement, which can be used by manufacturers producing based on RF power measurement and calibration and test laboratories accredited within the scope of RF power measurement, saving time and minimizing operator errors. It offers measurement uncertainty evaluation with Bayesian (GUM) and Monte Carlo Method approach, it is adaptable to specific measuring devices of project partners and is compatible with measurement equipment of major instrumentation vendors.
