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.
