Mode
More Information
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). It is also possible, using the same
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 test set. 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 test set 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 test set 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 test set program without changing your configured preloads. This may free up
enough memory to load the requested Mode, depending on your configured preloads
Backwards Compatibility SCPI: :INSTrument[:SELect] RECeiver
provided for ESU compatibility. When this command is received, the
analyzer aliases it to the following:
:INST:SEL EMI
:CONF FSC
This results in the analyzer being placed in the EMI Receiver Mode, running
the Frequency Scan measurement, in order to emulate the ESU Receiver
Mode.

Example: INST ‘SEQAN’?
Notes: The query is not a quoted string. It is an enumeration as indicated in the
Instrument Select table above.
The command must be sequential: i.e. continued parsing of commands cannot
proceed until the instrument select is complete and the resultant SCPI trees
are available.
