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 […]
by Chris Grachanen High speed data computations and routing rely on incredibly complex circuit board designs with data transfer rates fast approaching picosecond timing precision (that is one trillionth or one millionth of one millionth […]
by John Dorighi and Rob Sleigh An important consideration for improving the accuracy of time domain reflectometer (TDR) measurements is user calibration. A TDR user calibration is performed to correct for systematic instrument errors along […]
by Jesse Morse If a person making a dc or low frequency measurement fails to select the proper cables, or to properly connect the shields the traceability chain for that measurement can be violated. This […]
By Tom Morgan A method is derived for calculating the resistance tolerances for non-linear resistance scales, whose accuracy tolerances are given in degrees of arc instead of percent of reading or range. Read the Full […]
