by David F. Martson The development and use of intrinsic standards, e.g., Josephson Voltage Standard or JVS, has brought the primary level of uncertainty achievable for DC voltage down to a few nV/V (ppb), while […]
by Dan Wiswell We’ve all heard people speak of accuracies and tolerances in more colorful language than what would be expected in a metrology lab. “Plus-or-minus a hand grenade” or, “Close enough for government work” […]
EMPIR Capacity Building project Traceability Routes for Magnetic Measurements (TRaMM, 21SCP02) is a training project, where INRIM, the NMI for Italy, is transferring knowledge and expertise in the field of magnetic measurements and calibrations to […]
PTBnews 3.2023 Working within an industrial cooperation project, PTB has developed a novel metrology system for the quantum-based generation and measurement of voltage signals. The system is based on a pulse-driven Josephson standard, the Josephson […]
SANTA ROSA, Calif. September 18, 2023 Keysight Technologies, Inc. (NYSE: KEYS) introduces a new compact, four-channel vector signal generator (VSG) capable of signal generation up to 8.5 GHz with 960 MHz of modulation bandwidth per […]
Tokyo, Japan – August 7, 2023 — Yokogawa Test & Measurement Corporation announces the release of the DLM5000HD series high definition oscilloscopes. Positioned as a high-performance version of the DLM5000 series, the DLM5000HD series expands […]
by David Southworth Thermometry bridges play a crucial role in temperature measurement, particularly when it comes to the interpolation of the Standard Platinum Resistance Thermometer (SPRT) specified by the ITS-90. However, to achieve precise and […]
by Dan Wiswell As we all know, many years ago there was a time when there were no electrical testing instruments. I often think of how difficult it must have been for the pioneers of […]
