:SYSTem:PRESet
Description
Performs an instrument preset. This is the same function as provided by the front panel Preset key, or the ICON TOOLBAR | Preset icon, or the MENU BAR | Utilities | Preset command. No query. The type of preset performed depends on the type of preset set with the :SYSTem:PREset:TYPE command as either RESET or USER.
PRESet with RESET Set
If RESET has been is selected, the instrument returns to its factory as-shipped configuration, typically displaying one channel and four traces set to:
• Trace 1 (Tr1) set to S11 and a Smith Chart Impedance display.
• Trace 2 (Tr2) set to S12 and a dual rectangular display showing Log Magnitude and Phase graphs.
• Trace 3 (Tr3) set to S21 and a dual rectangular display showing Log Magnitude and Phase graphs.
• Trace 4 (Tr4) set to S22 and a Smith Chart Impedance display.
• Clears any user-defined segmented limit lines.
PRESET with USER Set
If USER has been selected, the instrument returns to a previously user-defined configuration state saved in either an All Channel Setup and Cal (CHA) file or in a All Channel Setup (STA) file.
No query.

:SYSTem:PRESet:TYPe <char>
:SYSTem:PRESet:TYPe?
Description
Sets the preset type to RESET, RESET0 (reset zero), or USER.
Returns the selected preset type.
The different preset types provide the following functions:
• USER – If the USER type is selected, a previously saved user-defined preset file must exist on the instrument disk drive. Once set, issuing a :SYSTem:PRESet command returns the instrument to the user-defined configuration. The user-defined preset file name is set using the :SYSTem:PRESet:FILe command.
• RESET – If the RESET type is selected, issuing a :SYSTem:PRESet command returns the instrument to the factory as-shipped configuration.
• RESET0 – If the RESET0 type is selected, issuing the :SYSTem:PRESet command clears the instrument memory of all calibration kit settings, calibrations, configurations, channel configurations, trace configurations, and other similar settings and returns the instrument to a factory as-shipped state. Functionally, issuing a :SYSTem:PRESet:TYPe RESET0 command followed by a :SYSTem:PRESet command is the same as issuing a :SYSTem:PRESet:ZERo command. Note that the RESET0 parameter does not delete any files. See the :SYSTem:PRESet:ZERo command description for a complete listing of included and excluded preset elements.
The preset type can also be configured by from the front panel by:
• Navigating to MAIN | System | SYSTEM | Setup | SETUP | Preset Setup | PRESET SETUP
• On the PRESET SETUP menu, selecting either Default, Default 0, or Saved Setup.
• If Saved Setup is to be used, the user-defined configuration file must be saved to the instrument solid-state drive. Then select the Select Saved Setup File button and select the desired user-defined preset file. Then select Saved Setup.
A preset can also be executed from the front panel by doing one of the following actions:
• Pressing the front panel Preset key.
• Selecting the ICON TOOLBAR | Preset icon.
• Selecting the MENU BAR | Utilities | Preset command.
Cmd Parameters
<char> RESET | RESET0 | USER

Syntax Example
:SYST:PRES:TYP RESET
:SYST:PRES:TYP?
:SYSTem:PRESet:ZERo
Description
Performs a Reset Zero which does not delete any files, but clears the instrument memory of all calibration kit settings, calibrations, configurations, channel configurations, trace configurations, and other similar settings and returns the instrument to a factory as-shipped state described in the command :SYSTem:PRESet. No query.
Similar to *RST
Similar to the *RST command, :SYST:PRES:ZER resets the instrument to a pre-defined condition with all user programmable command parameters set to their default values. These default parameter values are listed under each SCPI command in this manual.
Included Preset Conditions with :SYST:PRES:ZER
Except for the Command Parameters explicitly excluded in the next section, the :SYST:PRES:ZER command does the following:
• Sets the device-specific functions to a known state that is independent of the past-use history of the device;
• Device specific commands may be provided to program a different reset state than the original factory-supplied one;
• Clears any user-defined segmented limit lines;
• Sets the macro defined by *DDT to a device-defined state;
• Disables macros;
• Forces the device into the OCIS state (Operation Complete Command Idle State);
• Forces the device into the OQIS state (Operation Complete Query Idle State).
Excluded Preset Conditions with :SYST:PRES:ZER
The :SYST:PRES:ZER command DOES NOT make the following changes:
• Does not change the state of the IEEE 488.1 interface;
• Does not change the selected IEEE 488.1 address of the device;
• Does not change the Output Queue;
• Does not change any Event Enable Register settings including the Standard Event Status Enable Register settings;
• Does not change any Event Register setting including the Standard Event Status Register settings;
• Does not change the power-on-status-clear flag setting; and
• Does not change the Service Request Enable Register.
No query.

Syntax Example
:SYST:REF:TYPE?
:SYSTem:RETRace:RF[:STATe] <char>
:SYSTem:RETRace:RF[:STATe]?
Description
Sets the on/off state of the retrace RF energy.
The default normal RF Retrace State is OFF.
RF Retrace OFF – Normal Operation
During normal operation, the VNA makes a sweep from the lowest to the highest point and the starts over again at the lowest point. During the start over or retrace period or when switching bands, the RF energy is blanked.
The best is to operate totally within an oscillator band so that the forward portion and retrace can step through the same frequency list either forward or backward and there is no loss of RF energy. With RF Retrace OFF, the VNA provides good leveling performance and spur rejection.
RF Retrace ON – AGC Circuits
For faster sweep measurement response and/or increased protection in DUTs with AGC (automatic gain control) circuits, this command sets the RF Retrace State to ON. With this setting, the RF energy status remains on during the sweep, during band changes, and during the sweep reset from highest point to lowest point.With RF Retrace ON, the VNA does not offer less leveling performance and spur rejection.
