U.S. Government Rights
The Software is “commercial computer 
software,” as defined by Federal Acqui-
sition Regulation (“FAR”) 2.101. Pursu-
ant to FAR 12.212 and 27.405-3 and 
Department of Defense FAR Supple-
ment (“DFARS”) 227.7202, the U.S. 
government acquires commercial com-
puter 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 stan-
dard 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 Soft-
ware. The EULA and the license set 
forth therein, does not require or per-
mit, among other things, that Keysight: 
(1) Furnish technical information 
related to commercial computer soft-
ware or commercial computer software 
documentation that is not customarily 
provided to the public; or (2) Relinquish 
to, or otherwise provide, the govern-
ment rights in excess of these rights 
customarily provided to the public to 
use, modify, reproduce, release, per-
form, display, or disclose commercial 
computer software or commercial com-
puter software documentation. No 
additional government requirements 
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 pursu-
ant to the FAR and the DFARS and are 
set forth specifically in writing else-
where 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.
