Instrument Operating System
VXG Licensing Options
The server has a count for each license and will only allow instruments to
“check-out” a license up to that count. Once the count is reached for a specific
license, further check-outs fail until one of the licenses is checked back in to
the server. Therefore, it is possible for an instrument to have different features
available based on what licenses are available on the server when it tries to get
the licenses.
Setting up network licenses is done via the Keysight Floating License
Manager . Refer to the Installation Guide that can be downloaded from this web
page.
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 hardware. It
does not contain any writable data and so is acceptable to high security A/D
users. 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 on the one
instrument that has the dongle.
USB Portable licenses are identified in the product structure by an "U" in the
second character and either a "P" or an "L" in the third character, indicating a
term of either Perpetual or 1 year (12 months), respectively.
Example: N7631APPC-1UP
With USB portable licenses, the pre-installed Keysight Floating License
Manager is used to add licenses to the instrument’s server.
USB Portable licenses with a limited count 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.
USB Portable licenses that are "uncounted", will perform comparably to the
Fixed and Transportable licenses.
Plugging/un-plugging the dongle is equivalent to transporting a license
to/from the instrument, however, the application must be restarted whenever
the dongle is plugged in.
Configuring Network and USB Licenses
The Keysight Floating License Manager must be used to configure the Network
or USB Portable licenses before the licenses can be used. An instrument can
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”).
