Measuring the Capacitance Coefficients of Coaxial Open-circuits with Traceability to National Standards

Coaxial open-circuits are often used as measurement reference standards and can be found in most commercially available vector network analyzer (VNA) calibration kits. The capacitance characteristics of these devices are usually summarized in terms of ...
Coaxial open-circuit standards are found in many of today’s commercially available vector network analyzer (VNA) calibration kits. 1,2 They are most commonly used as standards in calibration schemes such as short-open-load-through (SOLT). In this capacity, they are assumed to have known characteristics, that is, they are assumed to provide...

Eliminating FFT Artifacts in Vector Signal Analyzer Spectra

This article presents a method to minimize the spectral leakage in measurements of periodic signals made with a vector signal analyzer (VSA) by taking into account the periodic nature of the Fast Fourier Transform (FFT). This method negates the need fo...
The vector signal analyzer (VSA) has several measurement advantages over a spectrum analyzer in the acquisition of bandpass RF signals, including its time-domain capture, which enables measurement of both magnitude and phase information, and its ability to display data in the time and frequency domains. 1,2 The highly sampled,...
