4.9.2 Power On/Preset
Displays keys that enable you to define the instrument power-on state and user preset
state.
NOTE If Power On is set to Preset, and Preset Type is set to Factory, then turning on
the analyzer performs a factory preset. The last state of the analyzer (before
it was turned off) is recalled if
Power On is set to Last. The user preset state is
recalled if
Power On is set to Preset and Preset Type is set to User. (However, if
there is no user preset state saved, the analyzer performs a factory preset.)

4.9.2.1 Power On
Enables you to set the state the analyzer will be put in when it is powered on. You can set
the state to Last or Preset.
If
Power On is set to Last, then the instrument returns to the last saved instrument state
and all the modes are restored to that last state. The instrument saves its current state
internally every 2 minutes. So the last saved state, that is restored at power-on, is the
state at power-off or within a maximum of two minutes before power-off.
If
Power On is set to Preset, the instrument state is determined by the preset type setting
prior to turning the power off.
• Preset type Factory powers on in the Spectrum Analysis mode and all modes are set to
their factory defaults.
• Preset type Mode powers on with the last mode the analyzer was in when it was
powered off and presets that mode to the factory defaults. It also restores all other
modes to their factory preset.
• Preset type User powers on with the user defined state, saved when a Save User Preset
was last performed.
The setting (Last or Preset) of the Power On function is not changed by pressing
Preset. Use
the
Power On/Preset menu key function to change the setting of the analyzer state that is
recalled at power on. Limit lines are not recalled when the analyzer is powered on. Refer to
“Preset” on page 211 for more information.
