by Christopher L. Grachanen Spreadsheets are one of the most prolific software tools used in calibration and test laboratories. From simple math computations and to sophisticated data curve fitting, spreadsheets are typically the de facto […]
by M. Zeier, J. Hoffmann, J. Ruefenacht, M. Wollensack The evaluation of measurement uncertainties in vector network analysis is a demanding task. The metrology guide EURAMET cg-12 (formerly EA 10/12) is dedicated to this topic […]
Over the years I have watched several labs go through the decision process to purchase new hardware. Most labs have the same process: look at the work load requiring the new hardware, and calculate the […]
The GUM Tree Calculator (GTC) is a data processing tool with full support for uncertainty calculations involving real and complex quantities. GTC is a stand-alone executable for Windows. It can handle instructions typedat the command […]
by Michael Schwartz Automation has its own quality system automatically built in. When software performs the same test, the same way over and over again, it can’t be wrong. There is no fake it till […]
by Michael Schwartz This paper covers the progress of the MII (Measurement Information Infrastructure) effort to create a standard for expressing a calibration laboratory capabilities, ISO/IEC 17025 Scope of Accreditation (SoA) in a XML formatted […]
by Michael Schwartz The next three technologies that will change the world as we know it will be artificial intelligence (AI) running in the cloud, working with the Internet of Things (IoT). Yes, that is […]
by Michael Schwartz Over the past 30 years of my software and automation career, I have migrated to a modular approach to software design. I come from an Object Oriented Programming (OOP) background and I […]
