Spectrum Analyzer - Keysight x-series User Reference Manual

5 Mode Functions
Mode
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:
1. 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
2. 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.
3. 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.
4. 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.
If you attempt to load a mode via SCPI that will exceed memory capacity, the Mode does not load and an
error message is returned:
–225,"Out of memory;Insufficient resources to load Mode (mode name)"
where "mode name" is the SCPI parameter for the Mode in question, for example, SA for Spectrum
Analyzer Mode.

Spectrum Analyzer

Selects the Spectrum Analyzer mode for general purpose measurements. There are several
measurements available in this mode. General spectrum analysis measurements, in swept and zero span,
can be done using the first key in the Meas menu, labeled Swept SA. Other measurements in the Meas
Menu are designed to perform specialized measurement tasks, including power and demod
measurements.
If you are using the Help feature, this mode must be currently active to access its detailed information. If it
is not active, exit the Help feature (Esc key), select the mode, and re-access Help.
