Measurement Software Toolkit

The Measurement Software Toolkit is a collection software tools designed to assist with the calculation of measurement uncertainty.

Various libraries and other software tools are available that implement a proprietary GUM Tree method (compatible with the Guide to the Expression of Uncertainty in Measurement).These include a stand-alone programmable uncertainty calculator, several add-ins for Microsoft Excel and a library for uncertainty calculation written in R.

A topic of particular interest is the calculation of uncertainty for complex-valued quantities. This is important in a number of areas, including AC electrical and RF and microwave measurements. The software provided here implements extensions of the standard real-valued methods that handle complex-valued problems.

There are also spreadsheet checking and validation tools. An Excel add-in has been designed for spreadsheet and worksheet function testing using assertions.
