Maury’s new line of Verification Kits allows for a more thorough and definitive validation.

Maury Verification Kits consist of the following verification standards and allow for 1-port and 2-port calibration validation for well-matched and mismatched DUTs:

• Loads (Male and Female)
• Offset Short (Male and Female)
• Beaded Airline (Male to Female)
• Beaded Mismatch (Male to Female)

The Importance of VNA Calibration Validation VNA calibration is performed to correct for the systematic imperfections which existing in all analyzers and allow for users to shift the reference plane from the instrument test ports to a user-defined reference plane. However, how can one be sure that the calibration performed will result in accurate measurements?

Validation is by far the most important step in a measurement process.

Conventional validation techniques rely on an estimate of the residual errors after a calibration, source match, directivity and tracking, and are typically evaluated by measuring peak-to-peak ripple through a TDR method. These techniques rely on an airline as the validation standard, and the accuracy of the validation can be severely impacted by how well the airline has been machined and handled.
