Calculating a Calibration Factor

Technicians and engineers use calibration factors when making measurements; but where do these calibration factors really come from?

Modern Architecture Advances Vector Network Analyzer Performance

Modern Vector Network Analyzer (VNA) architectures such as those based on Nonlinear Transmission Line (NLTL) samplers and distributed harmonic generators now offer a beneficial alternative to traditional sampling VNAs. They allow for a simplified architecture and also enable VNAs that are much more cost effective. It is shown that NLTL technology results in miniature VNA reflectometers that provide enhanced performance over broad frequency ranges, and reduced measurement complexity, providing VNA users a unique and compelling solution for their high-frequency measurement needs.
