10 Spectrum Emission Mask Measurement
User Preset
User Preset
Accesses a menu that gives you the following three choices:
•
User Preset – recalls a state previously saved using the Save User Preset function.
•
User Preset All Modes – presets all of the modes in the analyzer
•
Save User Preset– saves the current state for the current mode
In products that run multiple instances of the X-Series Application, all instances use the same location to
save User Preset state. So Save User Preset of one instance will overwrite the Save User Preset of
another instance.

Notes User Preset is actually loading a state, and in legacy analyzers, it was possible to load a state
without affecting the trace data, limit lines or correction data. Similarly it was possible to do a User
Preset without affecting the trace data, limit lines or correction data.
In the X-Series, “state” always includes all of this data; so whenever state is loaded, or User Preset is
executed, all of the traces, limit lines and corrections are affected. Although this differs from
previous behavior, it is desirable behavior, and should not cause adverse issues for users.
On ESA and PSA, User Preset affected the entire instrument’s state. In the X-Series, User Preset only
recalls the state for the active mode. There is a User Preset file for each mode. User Preset can never
cause a mode switch as it can in legacy analyzers. If you want to recall all modes to their user preset
file state, you will need to do a User Preset after mode switching into each mode.
User Preset recalls mode state which can now include data like traces; whereas on ESA and PSA,
User Preset did not affect data.

User Preset
User Preset sets the state of the currently active mode back to the state that was previously saved for this
mode using the Save User Preset menu key or the SCPI command, SYST:PRES:USER:SAV. It not only
recalls the Mode Preset settings, but it also recalls all of the mode persistent settings, and the
Input/Output system setting that existed at the time Save User Preset was executed.
If a Save User Preset has not been done at any time, User Preset recalls the default user preset file for the
currently active mode. The default user preset files are created if, at power-on, a mode detects there is no
user preset file. There will never be a scenario when there is no user preset file to restore. For each mode,
the default user preset state is the same state that would be saved if a Save User Preset is performed in
each mode right after doing a Restore Mode Default and after a Restore Input/Output Defaults.
The User Preset function does the following:
•
Aborts the currently running measurement.
•
Sets the mode State to the values defined by Save User Preset.
•
Makes the saved measurement for the currently running mode the active measurement.
•
Brings up the saved menu for the power-on mode.
