4.7.5 USB Portable Licenses
The USB Portable license is implemented with a physical dongle that is a USB
device, like a USB thumb drive. It has a Host ID fixed in the dongle HW. It does not
contain any writable data and so is acceptable to high security A/D customers.
Transporting licenses from one instrument to another just requires moving the
dongle and license files to the desired instrument. The license files can be installed
on many instruments, but they will only be valid the one instrument that has the
dongle. The use of USB portable licenses requires that the Keysight Floating License
Manager is installed on the instrument. The licenses can then be added to the
instrument’s server.
USB Portable licenses are checked out and in like Network licenses. Because the
licenses are local, there will be no network latency involved in the check-out/check-
in, but there can still be a slight performance degradation compared to Fixed and
Transportable licenses. If the instrument allows multiple concurrent instances of the
X-Series software (as is the case for modular products), there may also be
availability issues if all licenses are already checked out to other X-Series instances.
Plugging/un-plugging the dongle is equivalent to transporting a license to/from the
instrument, however, the software must be restarted whenever the dongle is
plugged in.
4.7.6 Configuring Network and USB Portable Licenses
The Keysight Floating License Manager must be used to configure the Network or
USB Portable licenses before the licenses can be used. Currently, an instrument can
only be configured for Network or USB Portable licenses or both.
–
To set up USB Portable licenses, in the Keysight Floating License Manager select
“Start a floating license server with a license file” and add files containing the
USB Portable licenses desired
–
To set up Network licenses, in the Keysight Floating License Manager select
“Connect to a floating license server” and enter the network server’s name
preceded by the “@” character (example: “@myserver”)
–
To set up both Network and USB Portable license, first configure the USB
Portable license, then configure the Network licenses, but append “;@localhost”
to the server name (example: “@myserver;@localhost”). Whenever the
configuration is changed, the X-Series software must be restarted
