Licensing New Measurement Application Software -  
After Initial Purchase
Additional measurement application software can be ordered after your initial 
purchase of the signal analyzer. Software upgrades are provided in a kit that 
includes an option based Entitlement Certificate and a license agreement. The 
licenses are downloaded from the license Web site onto a USB storage device 
so they can be loaded into the instrument.
For all new measurement application installations, we recommend that the 
latest version of the instrument software be installed. This ensures that the 
measurement application being licensed and activated is installed and is the 
most current version.
The latest revision of the software may be downloaded from:

A license key is usually for one Host ID only. The Host ID for Fixed and 
Transportable is the instrument model and serial number, for Network it is the 
server’s MAC address, and for USB Portable it is the USB Dongle’s number 
(printed on the dongle).
Installation procedure over USB for Fixed licenses
No calibration is required after a measurement application installation.
