X-parameters Open Documentation, Trademark Usage & Partnerships

X-parameters Open Documented Format & Equations

Agilent Technologies developed its X-parameters functionality to be an industry standard for nonlinear behavioral characterization and modeling. Agilent has published the equations underlying the theory behind the X-parameters functionality and the files are in an open, documented, non-encrypted, human readable format. All data generated from the legal use of Agilent products containing the X-parameter functionality is wholly owned by the customer. Agilent has taken these steps to enable broad industry adoption and to encourage others to join in the development of the technology. Several IEEE papers which discuss the technology and its application can be found by visiting IEEE Explore and searching for “X-parameters”. The open file format is documented and can be made available.

Because of the nature of the technology, it is possible for others to produce data in a file format that may appear to be similar to that used by Agilent's X-parameters functionality, but yet doesn’t accurately reflect the nonlinear behavior of the device. To this end, we have established formal relationships with industry partners and customers to ensure understanding and promote accurate commercial deployment.

Using The X-parameters Trademark

Agilent encourages industry partners, the academic** community and customers to write in industry publications and present at industry conferences about their use of Agilent's X-parameters* functionality and Agilent’s products that incorporate X-parameters functionality. Agilent’s permission is not required if articles or papers are authored based on factual use. Agilent does request that the first time the X-parameters trademark is used, that it is acknowledged with an asterisk (*) and the following footnote: * X-parameters is a registered trademark of Agilent Technologies.

Agilent does not grant permission to companies to claim or imply that they own, or sell similar products having functionality similar to Agilent’s X-parameters functionality or derivations thereof. Using the X-parameter trademark and brand in this way would require the written consent of Agilent Technologies.

Agilent’s X-parameters Industry Partnerships

Agilent and its partners use Agilent's X-parameters functionality to deliver superior nonlinear solutions through the combination of advanced technology, measurement solutions, and RF EDA design software for the measurement, generation and simulation of advanced designs and other applications.

Agilent welcomes additional industry partners. Benefits of direct collaboration with Agilent Technologies can include updates to the standard as it evolves, certification of the implementation, training, participation in joint activities hosted by Agilent, and general support. In some cases licensing of the X-parameters brand and technology is also possible. Given the rapidly developing state of the technology, as well as finite resources, Agilent currently can provide additional support only to key customers and strategic partners whose efforts are focused on improving the technology.
