METAS S-Parameter Metrology
Welcome to the METAS S-Parameter Metrology forum!
Scattering parameters are fundamental quantities in radio frequency and
microwave metrology. Traceability to SI units for these measurements is established
with the help of calculable standards. Progress has been made over the last
years in characterizing these standards. Major steps forward were achieved with
advanced modelling of the entire standard, including connector interface and
with the use of multivariate uncertainty evaluation, taking correlations fully into
account. The improvements have led to more consistent and more accurate measurements.
The goal of this forum is to make Vector Network Analyzer (VNA) users aware about the new findings in VNA metrology, to provide good measurement practice and how this is linked with our S-Parameter calibration services.

METAS VNA Tools II is a software designed to compute uncertainties of S-parameter measurements, see www.metas.ch/vnatools
