From 2002 to 2004 the Consultative Committee for Thermometry (CCT) carried out a Key Comparison (KC) of water triple point cells (CCT-K7). In 2005 Regional Metrology Organization (RMO) EURAMET decided initiate an additional KC cells, EUROMET.T-K7, extend metrological equivalence larger number national metrology institutes (NMIs) from region.
Radio Frequency (RF) power sensor calibration is one of the essential measurements in RF and microwave metrology. For a reliable accurate calibration, there are various methods, such as substitution method, direct comparison transfer method (DCTM), vector network analyzer (VNA)-based (VBCM). The VBCM that derived from DCTM. It preferred since VNA has better measurement capability fewer connection requirements for devices. In this study, milestones potential application errors given by...
RF power measurement is essential in and microwave metrology. For reliable accurate measurement, automatic preferred. A software application C#, named AutoRFPower, was developed for uncertainty calculations at this study. According to the GUM document, enhanced by utilizing Law of Propagation method Monte Carlo Simulation method. Trial measurements were performed different levels frequencies between 50 MHz 18 GHz using AutoRFPower software. carried out based on trial Oracle Crystal Ball...
AUTORFPOWER software has been developed for automatic RF power measurement at microwave frequencies. In this study, the capabilities of are explained and compared with commercial alternatives. The advantages to metrological works its contributions future R&D discussed.

In this paper the interlaboratory comparison in field of measurement temperature is presented. Within intercomparison calibration a SPRT at fixed points range from triple point argon 83.8058 K (−189.3442 °C) to freezing zinc 692.677 (419.527 was performed. The organized by University Ljubljana, Faculty Electrical Engineering, Laboratory Metrology and Quality (MIRS/UL-FE/ LMK). circulating items were two 25 Ω standard platinum resistance (SPRT) thermometers, one metal sheathed quartz...
Automatic RF power measurements have become indispensable for reliable and accurate in high frequency systems, which are increasingly used nowadays. In the project subject to this study, an automatic measurement software that can perform multiple has been developed. manual automatically by using developed evaluated also advantages of contributions uncertainty calculations presented.
Comparisons of indium freezing point cells have been carried out by the EUROMET TC-THERM group as Projects Nos 391 and 712. The main objective was to establish agreement between realizations within different participating laboratories, identify eliminate possible discrepancies. equipment has made available BNM?INM. Justervesenet coordinated project no 391, while 712 This paper is final report results obtained, including uncertainties in comparisons degrees equivalence laboratories. Main...
Commercial power sensors operating above 110 GHz frequencies have begun to be supplied due the development of communication systems. However, characterization these is still a problem solved. In this study, measurements performed for identification RF between and 170 according thermal principle studies determining parameters measurement uncertainty calculations based on are included. It has been shown that preformed with used in high long-term should take into account stability linearity sensor.
