by Flavio Galliana, Roberto Cerri, & Davide Corona At the National Institute of Metrological Research (INRIM) an automatable precision DC voltage fixed-ratios divider allows the division ratios of DC Voltages from 10:1 to 107:1. It […]
PTB News 2.2021 Josephson arbitrary waveform synthesizers (JAWS) allow quantized AC voltages to be synthesized with arbitrary and spectrally pure waveforms. At PTB, a pulse-driven Josephson standard for the generation of AC voltages with series […]
Summary Inconsistencies plague the mains power line, and these problems negatively impact the performance quality of electronic (as well as virtually any precision) equipment. Cleaning the power results in one less potential source of error […]
Denver, Colorado (February 2021) – Electronics innovator KCC Scientific LLC launches the new Mercury 1000 Voltage and Frequency Converter, supporting precision electronic equipment up to 1000 watts. The Mercury family of converters are capable of […]
by Michael Schwartz & Jack Somppi Changing requirements in the world’s energy market are pushing the measurement performance of existing equipment to their limits. As the accuracy requirements increase, existing precision sources become marginal. Yet, […]
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 Rado Lapuh There is often a need in metrology to use a high precision sampling digital multi-meters in order to look at the amplitude, frequency and phase of a sinewave signal in detail. But […]
