Calibrating VNAs is an important step in making accurate measurements with vector network analyzers. We find many people have good questions on the proper calibration of USB VNAs. We felt this topic was so important that CMT Senior RF Design Engineer Brian Walker conducted a webinar about the different types of calibration for network analyzers. The types of calibration that were covered were:

• SOLT/SOLR Calibration
• TRL Calibration
• Waveguide Calibration

He also reviewed in the webinar how the standards for calibration are defined. The advantages and setbacks of different types of calibrations were also covered in this webinar.
