Information on the Data-Based Cal Kit EditorThis Calibration Kit Editor, now part of firmware A.04.06 and above, allows the creation of cal kits that include data-based standards. Data-based standards are described by a data list. A data-based standard should include a list of frequencies, the actual response for each s-parameter at each frequency and an estimate of the accuracy of the actual response to be used in determining the weighting factor used by expanded cal. Currently, only one-port data-based devices are supported. Support for two-port devices will be added later. The download link is at the bottom of this page.

This program can be installed on either a PC or the PNA itself. The regular CalKit Editor, which is available on the Applications page, now includes this capability. It is also part of the A.04.06 firmware which was released in December 2003. ![]() |
