6 List Sequence Measurements
Mode Preset
Mode Preset
Returns the active mode to a known state.
Mode Preset does the following for the currently active mode:
•
Aborts the currently running measurement.
•
Brings up the default menu for the mode, with no active function.
•
Sets measurement Global settings to their preset values for the active mode only.
•
Activates the default measurement.
•
Brings up the default menu for the mode.
•
Clears the input and output buffers.
•
Sets Status Byte to 0.
Mode Preset does not:
•
Cause a mode switch
•
Affect mode persistent settings
•
Affect system settings
•
See
for more information.

Remote Command
:SYSTem:PRESet
Example
:SYST:PRES
Notes
*RST
is preferred over :
SYST:PRES
for remote operation. *RST does a Mode Preset, as done by
the :SYST:PRES command, and it sets the measurement mode to Single measurement rather than
Continuous for optimal remote control throughput.
Clears all pending OPC bits. The Status Byte is set to 0.
Couplings
A Mode Preset aborts the currently running measurement, activates the default measurement, and.
gets the mode to a consistent state with all of the default couplings set.
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 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
