Hundreds of engineers and scientists trust in VNA Tools
The knowledge of Vector Network Analyzer (VNA) measurement uncertainties is crucial to make statements about the conformity of devices and components. VNAs cover an increasing range of measurement applications in the high-frequency range. VNA Tools, as a leading metrology software, keeps up with this development – since over ten years.

Uncertainty Library (UncLib)
VNA Tools is built on METAS UncLib. UncLib is a free measurement uncertainty calculator for the propagation of measurement uncertainties. It can be used in wide range of metrological fields and is not limited to S-parameter measurements.
Simplify integration with the Real Time Interface (RTI)
In addition to the free software VNA Tools, METAS has recently extended the software with a new licensable tool: The Real Time Interface (RTI). It simplifies the implementation of VNA Tools into an existing software environment. Commercial solutions using VNA Tools RTI have become available.
