Software Summary

A brief description of each program is provided. Select the program (right menu box) for more complete details with access to the downloadable file.

Mismatch Calculator assists your determination of the accuracy of microwave power and impedance measurements.

Tolerance Calculator establishes suitable test limits for a defined confidence level and is particularly useful where the ratio between product specification and uncertainty is low.

Uncertainty Calculator enables the assessment of measurement accuracy and presents the budget and calculations in a form consistent with international standards.

Conversion Buddy provides an intelligent lookup utility to translate measurement units.

Expression Buddy will take a user-defined mathematical formula and determine its result and  standard error.

GUM Workbench provides for calculation of uncertainty in a manner that is internationally recognized and offers user-friendly entry of variables for the measurement formula.

Variation is an educational program that introduces aspects of statistical process control.

VNA Uncertainty is an MS-Excel97 add-in created by Agilent to ease the determination of measurement accuracy for Vector Network Analyzers.

Evaluatorcan estimate uncertainties, fit data, solve expressions, plot
graphs, display tables, do statistics (with functions used in metrology), do bit-wise and logical calculations and run script files. Aimed particularly at metrology users, uncertainty estimation follows both ISO and Monte-Carlo methods.

Predictor enables metrologists to estimate present values and
uncertainties of measurment standards based on their past calibrations. It can also estimate recalibration intervals and issue calibration reports.

SWR Calculator has a similar purpose to the Mismatch Calculator but with a visual interface that resembles the original HP slide-rule.

UnCalc is an Excel spreadsheet to assist in the calculation of measurement uncertainty. A paper is also available that describes its use.
