Preset Menu 

Preset is a convenient facility to store multiple configurations which can be easily recovered. 

Identifier: Numerical index of the preset valid from 1-100 (

SPA-50K

) or 1-30 (

SPA-3G, SPA-6G

)

Description: Descriptive text up to 12 characters long. An asterisk at the end is automatically added
when the preset has actually some data stored. In Plus model, this field is editable and can be
changed in the device. In Combo models, this field is read only and can only be updated with the
external Preset Manager tool.

Load: Action option to load stored preset values into current configuration, the menu screen is
automatically closed

Save: Action option to save current configuration into the selected preset – this option cannot be
undone, care should be taken to not overwrite another valid preset

Reset: Action option to remove all values from selected preset and reset to unused state - this option
cannot be undone, care should be taken to not reset a valid preset

Frequency range: when an active preset with data stored is selected, the last line of the screen
shows the Start/Stop frequency range of the preset, to help on determining the specific preset
configuration before using it. This line will be blank when an empty preset is selected.

Easy Preset restore: 

This menu has a very convenient shortcut for easy selection and restore of any pre-defined preset:

menu

 

becomes active and cursor is preselected in

 action option. Pressing SET button inside this

menu

 

will iterate through all predefined Presets with valid data one by one. This shortcut is faster

than

 

manually changing 

Identifier

 numbers one by one when you are looking to load a preset.

SPA-3G and SPA-6G 

models: These models do not have a dedicated SET button, but an

equivalent function is

 

available by clicking ENTER button on 

Desc:

 line, the menu will iterate through
