by Donald Larson Many digital oscilloscopes have the capability of acquiring, displaying, and storing a digitized representation (the waveform) of an electrical signal. This digitization creates data, the waveform samples, that have discrete amplitude values […]
PTBnews 3.2018 – PTB is developing a measuring system based on pulse-driven Josephson voltage standards. This system is designed to allow alternating voltages to be measured with great accuracy at frequencies of up to 100 […]
An international collaboration, including researchers from the National Physical Laboratory (NPL) and Royal Holloway, University of London, has successfully demonstrated a quantum coherent effect in a new quantum device made out of continuous superconducting wire […]
At the heart of every electronic weighing instrument is a device called a load cell, which takes a mechanical force and turns it into an electronic signal. Anytime something needs to be weighed in commerce […]
by Jerry Eldred Although rise time is a common calibration measurement in pulse/function generators and some oscilloscopes, it is often not well understood. Making a good rise time measurement is somewhat similar to home stereo […]
by Michael Johnston Due to the high accuracy of the long scale (8½-digit) meters, the standards and methods required to perform a verification of the device often make automation of the process difficult. Alternatively, guardbanding […]
WASHINGTON, D.C., June 20, 2017 — In the last decades, mobile phones and other wireless devices have become central features of life around the globe. These devices radiate varied amounts of electromagnetic energy and thus […]
The robust, handheld R&S Scope Rider now combines the functionality of eight instruments, making it the most versatile oscilloscope in its class. New features include a spectrum analyzer, a frequency counter and a harmonic analyzer […]
