Preloading Applications
During runtime, if a Mode that is not preloaded is selected using the Mode menu or
by sending SCPI commands, there will be a pause while the Application is loaded.
During this pause, a message that says “Loading application, please wait
…” is displayed. Once loaded, the application stays loaded, so the next time you
select it during a session, there is no delay.
Preloading lets you “preload” at startup, to eliminate the runtime delay. Preloading
an application causes it to be loaded into the instrument’s memory when the
analyzer program starts up. If you do this, the delay will increase the time it takes to
start up the analyzer program, but this may be preferable to having to wait the first
time you select an application. Note that, once an application is loaded into
memory, it cannot be unloaded without exiting and restarting the analyzer program.
Note that there are more applications available for X-Series than can fit into
Windows Virtual Memory. By allowing you to choose which licensed applications to
load at startup, the Configure Applications utility allows you to make optimal use of
the instrument memory.
Access to Configure Applications utility
A version of the utility runs the first time you power up the instrument 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.
At any time, you can manually start the Configure Applications utility by closing the
analyzer application and double-tapping the Configure Applications icon on the
desktop.
The utility’s main dialog looks like this:
