Agilent 81133A/81134A Pulse Generator User’s Guide, September 2008 85
Updating the Firmware 
Firmware updates of the instrument can be done by using one of 
the supported programming interfaces. 
Updates and patches are available on the Agilent Web at:
http://www.agilent.com/find/pulse_generator 
They are applied by downloading the update/patch from the web 
(single executable) and running it. 
The connection path to the instrument is queried for the time the 
executable is run. A warning is issued if a new firmware revision 
would be overwritten by an older one. Nevertheless, this down-
grade can be forced.
Prerequisites
The instrument must be connected to a PC through one of the 
supported remote programming interfaces. The operating system 
running on the PC must be either Windows NT, Windows 2000, or 
Windows XP.
An upgrade/patch always includes all parts of the software (that is 
firmware and BIOS).
