Mode Preset
How-To Preset
The table below shows all possible presets, their corresponding SCPI commands and front-panel access
(key paths). Instrument settings depend on the current measurement context. Some settings are local to
the current measurement, some are global (common) across all the measurements in the current mode,
and some are global to all the available modes. In a similar way, restoring the settings to their preset state
can be done within the different contexts.
Auto Couple - is a measurement local key. It sets all Auto/Man parameter couplings in the measurement
to Auto. Any Auto/Man selection that is local to other measurements in the mode will not be affected.
Meas Preset - is a measurement local key. Meas Preset resets all the variables local to the current
measurement except the persistent ones.
Mode Preset - resets all the current mode's measurement local and measurement global variables
except the persistent ones.
Restore Mode Defaults - resets ALL the Mode variables (and all the Meas global and Meas local
variables), including the persistent ones.
Backwards Compatibility Notes: In the X-Series, the legacy “Factory Preset” has been replaced with Mode
Preset, which only presets the currently active mode, not the entire instrument.
In the X-Series, the way in to preset the entire instrument is by using System,
Restore System Defaults All, which behaves essentially the same way as
restore System Defaults does on ESA and PSA.
There is also no “Preset Type” as there is on the PSA. There is a green Mode
Preset front-panel key that does a
Mode Preset and a white-with-green-letters
User Preset front-panel key that does a User Preset. The old PRESet:TYPE
command is ignored (without generating an error), and SYST:PRES without a
parameter does a Mode Preset, which should cover most backward code
compatibility issues.
The settings and correction data under the Input/Output front-panel key
(examples: Input Z Corr, Ext Amp Gain, etc.) are no longer part of any Mode,
so they will not be preset by a Mode Preset. They are preset using Restore
Input/Output Defaults, Restore System Defaults All. Note that because User
Preset does a Recall State, and all of these settings are saved in State, they
ARE recalled when using User Preset.
