NEW PRODUCT RELEASE: UncertaintyToolbox™ Version 3.33 is now available! Now compatible with Excel 2013, 2010, 2007SP1 and Office 365 (Desktop Version). New features provides full functionality with industry specific Custom Templates. A Sample Custom Template is included, which is used to estimate uncertainty of measurement due to RF Impedance Mismatch. This template is based on the White Paper titled "Revisiting Mismatch Uncertainty with the Rayleigh Distribution". (A copy of the paper is embedded in the spreadsheet.)
The included RF/Microwave "Mismatch Uncertainty" Template replaces the previously recommended use of the U-Shaped Distribution, as it provides a more accurate estimate. The complexity in computation of the resulting standard uncertainty using the Rayleigh Distribution, combined with its limited use in RF/Microwave Power measurements, made it the perfect choice for our example "Custom Template". We continually improve UncertaintyToolbox™ to make the task of computing measurement uncertainty for all types of measurements easier, Custom Templates provide one more tool for us to use in achieving that objective.Over 1000 laboratories around the world, use UncertaintyToolbox™ to meet the measurement uncertainty analysis requirements of ISO/IEC17025 laboratory accreditation.
Our Software User Groups Area provides support for QUAMETEC™ Microsoft® Excel® VBA based Metrology Software. UncertaintyToolbox™ is a trademark of the Quametec Corporation.
