by Ronald Ginley Volume 6:5, Sep-Oct 1999 Verification of Vector Network Analyzers (VNAs) is very important to the measurement process as well as to establish confidence in the uncertainty of the system. This paper presents […]
Introduction Copper Mountain Technologies produces lab-grade VNAs with outstanding measurement accuracy. As with every VNA, performing a good calibration is necessary for maximizing the accuracy of VNA measurement results, for de-embedding the effects of imperfect […]
Engineers at the National Institute of Standards and Technology (NIST) have developed a flexible, portable measurement system to support design and repeatable laboratory testing of fifth-generation (5G) wireless communications devices with unprecedented accuracy across a […]
by Brian Walker Calibration methodology for Vector Network Analysis has evolved over the years. The first calibrations were simple normalizations. Later, with a better understanding of the systematic errors a calibration methodology involving the measurements […]
by Christopher L. Grachanen Vector Network Analyzers (VNA) are used to measure a variety of RF parameters such as transmission loss, reflection loss, phase and group delay for a variety of passive RF devices and […]
Researchers at the National Institute of Standards and Technology (NIST) have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the stability of microwave signals a hundredfold. […]
By adding the R&S NRP90T und R&S NRP90TN models to its portfolio of thermal power sensors, Rohde & Schwarz releases the very first test and measurement instruments in the market to support the novel, robust 1.35 […]
