by Rich Pieciak and Kay-Uwe Sander Volume 12:3, Jul-Sep 2005 As a fundamental tool of virtually every microwave and many digital design engineers, the accuracy of a signal generator is critical, whether in the laboratory, […]
by William M. Kilpatrick Volume 11:3, Jul-Sep 2004 When Hewlett-Packard introduced the HP 8902A measuring receiver in 1981, IBM had just announced the personal computer, the World Wide Web was just a glimmer in the […]
by Dave Abell and Jon Moens Volume 9:4, Oct-Dec 2002 Calculating measurement uncertainties for a single parameter such as DC voltage is relatively straightforward, but to do so for a complex microwave spectrum analyzer that […]
by Jeff Gust Volume 7:5, Sep-Oct 2000 As metrologists are acutely aware, when one transfers a measured value such as resistance, they also transfer a measurement uncertainty that is associated with the calibration of the […]
by Peter B. Crisp Volume 6:5, Sep-Oct 1999 Many organizations rely on 10V DC standards as their primary DC reference. However, the routine maintenance of such devices is not only labor intensive, but requires a […]
by A.J. Wallard and T.J. Quinn Volume 6:6, Nov-Dec 1999 Concern has grown in recent years over the assertion by manufacturers of quantum-based commercial equipment that these products are intrinsic standards. A.J. Wallard, Deputy Director […]
Large capacity rack allows longer walk-way measurement time Dual robotic arm save time by collecting up to four test weights and a reference weight for simultaneous measurement Modular, compact design provides three systems to suit […]
In the past 20 years, having a digital representation of a calibration certificate has been a topic of discussion. I remember attending my very first NCSLI Workshop & Symposium in 2001 and sitting in on […]
