Instrument Boot Up Process

This section describes the signal analyzer boot up process from initial AC
power to a normal analyzer sweep. The boot process time from start to finish
will take 3 to 4 minutes. This boot time will vary depending on the analyzer
hardware configuration, installed options and the number of measurement
applications.
By default, the measurement applications will preload before the noise figure
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. You must close the Xsa application to configure applications. One way
to do this is to call up Task Manager, highlight the Xsa.exe application and
select Close. Once the Xsa application closes, you can view the desktop, which
has a Configure Application icon. Select Configure Applications. This will bring
up a window as shown in
what is selected to preload. By default all applications are checked and
therefore, will preload when the XSA application is launched. Uncheck any
applications to bypass the preloading process, select Apply, and then OK to
close the Configure Applications window when finished.
