“…These devices in the VNA show that the VNA contains most of the devices needed by the DCTM, which is the method used to determine the CF value of the DPS. The VNA-based CF determination method (VBCM) was developed based on the idea of simultaneously measuring the reflection coefficients and performing the necessary measurements for the DCTM, which is necessary to calculate the DPS's CF using the VNA [8][9][10].…”

“…The SM and DCTM are both well-known power sensor calibration methods used in the metrological domain. On the other hand, the VBCM is a newer method and has recently been utilized in some new R&D projects (EMPIR 20IND03 Futurecom) [11], as well as in some national metrology institutes, such as KRISS, South Korea, and TUBITAK UME, Türkiye [8,9]. The VBCM is a preferred method since the VNA has a better measurement capability and has fewer connection requirements for measurement devices [9].…”

Radio Frequency (RF) power sensor calibration is one of the essential measurements in RF and microwave metrology. For a reliable and accurate power sensor calibration, there are various methods, such as the substitution method, the direct comparison transfer method (DCTM), and the vector network analyzer (VNA)-based calibration method (VBCM). The VBCM is a method that is derived from the DCTM. It is a preferred method since the VNA has a better measurement capability and has fewer connection requirements for measurement devices. In this study, the milestones and potential application errors of the VBCM are given by considering the connection mistakes, measurement faults, calculation errors, and control software coding problems. At the end of the power sensor calibration measurements with the VBCM, the model function components and the uncertainty calculation examples according to the GUM Bayesian method are also presented in this study. In addition, the advantages and disadvantages of the VBCM compared to the former methods are discussed in this study.
