license and may be used or copied only in 
accordance with the terms of such license.
U.S. Government Rights
The Software is “commercial computer 
software,” as defined by Federal Acquisition 
Regulation (“FAR”) 2.101. Pursuant to FAR 
12.212 and 27.405-3 and Department of 
Defense FAR Supplement 
(“DFARS”) 227.7202, the U.S. government 
acquires commercial computer software 
under the same terms by which the 
software is customarily provided to the 
public. Accordingly, Keysight provides the 
Software to U.S. government customers 
under its standard commercial license, 
which is embodied in its End User License 
Agreement (EULA), a copy of which can 
be found at: 
http://www.keysight.com/find/sweula. 
The license set forth in the EULA represents 
the exclusive authority by which the U.S. 
government may use, modify, distribute, or 
disclose the Software. The EULA and the 
license set forth therein, does not require 
or permit, among other things, that 
Keysight: (1) Furnish technical information 
related to commercial computer software 
or commercial computer software 
documentation that is not customarily 
provided to the public; or (2) Relinquish to, 
or otherwise provide, the government 
rights in excess of these rights customarily 
provided to the public to use, modify, 
reproduce, release, perform, display, or 
disclose commercial computer software or 
commercial computer software documen-
tation. No additional government require-
ments beyond those set forth in the EULA 
shall apply, except to the extent that those 
terms, rights, or licenses are explicitly 
required from all providers of commercial 
computer software pursuant to the FAR and 
the DFARS and are set forth specifically in 
writing elsewhere in the EULA. Keysight 
shall be under no obligation to update, 
revise or otherwise modify the Software. 
With respect to any technical data as 
defined by FAR 2.101, pursuant to FAR 
12.211 and 27.404.2 and DFARS 227.7102, 
the U.S. government acquires no greater 
than Limited Rights as defined in FAR 
27.401 or DFAR 227.7103-5 (c), as 
applicable in any technical data.
