Presetting the Spectrum Analyzer

Preset provides a known starting point for making measurements. The analyzer has three types of preset:

Factory Preset Restores the analyzer to its factory-defined state.

User Preset Restores the analyzer to a user-defined state.

Mode Preset This type of preset restores the currently selected mode to a known state.

For details, see the User’s/Programmer’s manual.

When Preset Type is set to Factory, pressing the green Preset key triggers a factory preset. When Preset Type is set to User, pressing Preset displays the softkeys Factory Preset, User Preset, and Mode Preset (if applicable); you then select the preset you want. If Preset Type is set to Mode, but a personality is not installed, pressing Preset triggers a factory preset.

Creating a User Preset

If you constantly use settings which are not the factory defaults, use the following steps to create a user-defined preset:

1.Set analyzer parameters as desired.

2.Press System, Power On/Preset, Save User Preset to set the current parameters as the user preset state.

3.Press Preset to select User in the same softkey menu to enable user preset as an option.

Disabling User Preset

Go to the Power On/Preset menu (press System, Power On/Preset) and select a Preset Type of Factory or Mode.
