48 X-Series EMI Receiver Getting Started GuideInstrument Operating SystemKeysight X-Series EMI Receiver LicensingThe 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 specificlicense, further check-outs fail until one of the licenses is checked back in tothe server. Therefore, it is possible for an instrument to have different featuresavailable to it based on what licenses are available on the server when it triesto 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.Application licenseApplication licenses (like N6141EM0D-1NP) are automatically checked outwhen entering the mode that uses them, and they are automaticallychecked-in when leaving that mode. Because the server may have alreadychecked out the last license for the application to another instrument, there isa possibility that a mode switch will fail because a required license could notbe checked out from the server. If the server has a limited number of licensescompared to the number of users desiring to use that license, this may meanthat switching from mode A to mode B then back to mode A may fail whenreturning to mode A because another instrument checked out the lastavailable license while the user was in mode B. Also, for modes with multiplelicenses for different features (like Multi-Standard Radio), the featuresavailable may also change when switching out of the mode and back into it.USB Portable LicensesThe USB Portable license is implemented with a physical dongle that is a USBdevice like a USB thumb drive. It has a Host ID fixed in the dongle hardware. Itdoes not contain any writable data and so is acceptable to high security A/Dcustomers. Transporting licenses from one instrument to another just requiresmoving the dongle and license files to the desired instrument. The license filescan be installed on many instruments, but they will only be valid on the oneinstrument that has the dongle.USB Portable licenses are identified in the product structure by an "U" in thesecond character and either a "P" or an "L" in the third character, indicating aterm of either Perpetual or 1 year (12 months), respectively.Example: N6141EM0D-1UPWith USB portable licenses, the pre-installed Keysight Floating LicenseManager is used to add licenses to the instrument’s server.USB Portable licenses with a limited count are checked out and in like Networklicenses. Because the licenses are local, there will be no network latencyinvolved in the check-out/check-in, but there can still be a slight performancedegradation compared to Fixed and Transportable licenses.USB Portable licenses that are "uncounted", will perform comparably to theFixed and Transportable licenses.
