Access to Configure Applications utility
A version of the utility runs the first time you power up the analyzer after purchasing it from Keysight. The
utility automatically configures preloads so that as many licensed applications as possible are preloaded
while keeping the total estimated virtual memory usage below the limit. This auto-configuration only takes
place at the very first run, and after analyzer software upgrades.
You may, at any time, manually call up the Configure Applications utility by pressing System, Power On,
Configure Applications, to find a configuration that works best for you, and then restart the analyzer
program.
The utility may also be called if, during operation of the analyzer, you attempt to load more applications
than can fit in memory at once.
Virtual memory usage
There are more applications available for the X-Series than can fit into memory at any one time, so the
Configure Applications utility includes a memory tracker that serves two purposes:
1. It will not let you preload more applications than will fit into memory at once.
2. You can determine how many of your favorite applications can reside in memory at one time.
The utility provides a graphical representation of the amount of memory (note that the memory in question
here is Virtual memory and is a limitation imposed by the operating system, not by the amount of physical
memory you have in your analyzer). You select applications to preload by checking the boxes on the left.
Checked applications preload at startup. The colored fuel bar indicates the total memory required when
all the checked applications are loaded (either preloaded or selected during runtime).
Here is what the fuel bar colors mean:
RED: the applications you have selected cannot all fit into the analyzer’s memory. You must deselect
applications until the fuel bar turns yellow.
YELLOW: the applications you have selected can all fit into the analyzer’s memory, but there is less than
10% of the memory left, probably not enough to load any other applications, either via preload or by
selecting a Mode while the analyzer is running..
GREEN: The indicator is green when <90% of the memory limit is consumed. This means the applications
you have selected can all fit into the analyzer’s memory with room to spare. You will likely be able to load
one or more other applications without running out of memory.
Select All
Marks all applications in the selection list. This allows you to enable all applications licensed on the
instrument for pre-loading, or is a convenience for selecting all applications in one operation and then
letting you deselect individual applications.
