APPL SETUP
RECOVERY
The APPL SETUP RECOVERY (Application Setup Recovery) softkey controls the
instrument behaviour when changing the active application, e.g from SPECTRUM to
FM DEMOD and back from FM DEMOD to SPECTRUM.
In the default state OFF a few parameters of the current analyzer setting are passed
to the application (e.g. center frequency, level settings) or from the application back
to the analyzer mode.
If APPL SETUP RECOVERY is switched ON, the settings of the applications are
independent of each other. Leaving the FM DEMOD application will restore the pre-
vious state of the ANALYZER.
