More Information
The Mode name appears on the banner after the word "Agilent" followed by the Measurement Title. For
example, for the Spectrum Analyzer mode with the Swept SA measurement running:
It is possible to specify the order in which the Modes appear in the Mode menu, using the Configure
Applications utility ( System, Power On, Configure Applications
utility, to specify a subset of the available applications to load into memory at startup time, which can
significantly decrease the startup time of the analyzer. During runtime, if an application that is not loaded
into memory is selected (by either pressing that applications Mode key or sending that applications
:INST:SEL command over SCPI), there will be a pause while the Application is loaded. During this
pause a message box that says "Loading application, please wait..." is displayed.
Each application (Mode) that runs in the X-Series signal analyzers consumes virtual memory. The
various applications consume varying amounts of virtual memory, and as more applications run, the
memory consumption increases. Once an application is run, some of its memory remains allocated even
when it is not running, and is not released until the analyzer program (xSA.exe) is shut down.
Agilent characterizes each Mode and assigns a memory usage quantity based on a conservative estimate.
There is a limited amount of virtual memory available to applications (note that this is virtual memory
and is independent of how much physical RAM is in the instrument). The instrument keeps track of how
much memory is being used by all loaded applications – which includes those that preloaded at startup,
and all of those that have been run since startup.
When you request a Mode that is not currently loaded, the instrument looks up the memory estimate for
that Mode, and adds it to the residual total for all currently loaded Modes. If there is not enough virtual
memory to load the Mode, a dialog box and menu will appear that gives you four options:
Close and restart the analyzer program without changing your configured preloads. This may free up
enough memory to load the requested Mode, depending on your configured preloads
Clear out all preloads and close and restart the analyzer program with only the requested application
preloaded, and with that application running. This choice is guaranteed to allow you to run the requested
application; but you will lose your previously configured preloads. In addition, there may be little or no
room for other applications, depending on the size of the requested application.
Bring up the Configure Applications utility in order to reconfigure the preloaded apps to make room for
the applications you want to run (this will then require restarting the analyzer program with your new
configuration). This is the recommended choice because it gives you full flexibility to select exactly
what you want.
Exit the dialog box without doing anything, which means you will be unable to load the application you
requested.
In each case except 4, this will cause the analyzer software to close, and you will lose all unsaved traces
and results.
