Calibration Apparatus And Calibrating Cross-Frequency Phases Of Large-Signal Network Analyzer Measurements
Patent Number: 11,536,793
Problem
The method overcomes the limitation on the spacing of the calibration frequency grids inherent in the current approach of using difficult-to-manufacture comb generators to calibrate the phases of large-signal network analyzers.
Invention
This invention accurately calibrates the cross-frequency phases of large-signal network analyzers on arbitrarily fine frequency grids.
Potential Commercial Applications
This method makes it ideal for application by a variety of instrument manufacturers, large and small.
Competitive Advantage
The method is based on easily obtained commercial instrumentation and can be easily applied to any instrument made by any manufacturer without using proprietary and difficult-to-manufacture comb-generator technologies currently in use.
