Thank you for your article! Well written and clear!
I have three questions:
1) You talk about calibrating the VNA using a kit.
But doesn't this Kit need periodic calibration? Do its components not degrade over time?
2) In a laboratory that, for example, has a VNA (2 or 4 ports) for checking cables, how do you ensure the claibration of the VNA to comply with the ISO/IEC17025: 2017 accreditation standard that requires measurement traceability?
3) How to calculate measurement uncertainty with the VNA according to the rules of SO/IEC17025: 2017 (EA-4/02 M: 2022: Evaluation of the Uncertainty of Measurement in calibration)? Do you know literature about this?
