UXA Instrument Boot Up Process
This section describes the N9040B Signal Analyzer boot up process from initial
AC power to a normal analyzer sweep. The boot process time from start to
finish will take 6 to 8 minutes. This boot time will vary slightly depending on
the analyzer hardware configuration, installed options and the number of
measurement applications.
By default, the measurement applications will preload before the spectrum
analyzer application is fully booted. The analyzer boot time can be shortened if
needed by turning off the preload process for applications that are not going to
be used. If this is done, the preload process will be bypassed during the
application boot up. If a certain measurement mode is selected that did not
preload during the original boot, that measurement application will preload at
that time. When this occurs the mode switching time will take longer. Once the
application is loaded all subsequent mode switches will be much faster.
If the user does not want the measurement applications to preload during the
application boot process, select the Configure Applications icon on the
desktop. This will bring up a window as shown in Figure 2-1 that shows the
various applications and what is selected to preload. By default all applications
are checked and therefore, will preload when the UXA application is launched.
Uncheck any applications to bypass the preloading process, select Apply, and
then OK to close the Configure Applications window when finished.
