SYSTem:PRESet[:DUMMy]
Performs a factory preset of all instrument settings (i.e. all open recall sets) or of the active
recall set, depending on the
SYSTem:PRESet:SCOPe
settings. The command is equiv-
alent to
*RST
and to the action of the PRESET key on the front panel.
Note:
If a user-defined preset is active (
ON
), the
PRESET
key initiates a user-defined preset, while
SYSTem:PRESet[:DUMMy]
and
*RST
still activate the factory preset. If "Align *RST to User Defined Preset" is selected
in the "System Configuration > Presets" dialog and a valid user preset file is available,
*RST
and
SYSTem:PRESet[:DUMMy]
also restore the user-defined settings.
Example:
SYST:PRES:SCOP SING
Define the scope of a preset: the active recall set is reset only.
SYST:PRES
Reset the parameters of the current recall set.
Manual operation:
See
SYSTem:SETTings:UPDate
<Activate>
Initiates an immediate update of the channel or trace settings.
The command has an effect if the analyzer operates in single sweep mode (
OFF
) and if the display update is switched off (
OFF
). In this scenario, a change of the channel or trace settings is
usually not taken into account immediately. The analyzer waits until the end of the current
sweep sequence and changes all settings made during the last sweep period when the
next single sweep sequence is initiated. Several settings can be made en bloc, which
generally saves time.
SYSTem:SETTings:UPDate ONCE
causes the analyzer to apply the settings at once
without waiting for the end of the current single sweep sequence. The command has no
effect in continuous sweep mode or if the display update is switched on.
The settings are also updated when the continuous sweep mode is activated (
ON
).
Setting parameters:
<Activate>
ONCE
Causes an immediate update of the settings.
Example:
INIT:CONT OFF
Activate single sweep mode.
SYST:SETT:UPD ONCE
Update the settings made during the current single sweep period.
Usage:
Setting only
SYSTem:SHUTdown
Switches the R&S ZNC to standby state.
