The two check boxes in the U
s
er Settings panel switch the instrument messages or transparent
info fields on or off. The Instrument Messages setting is also valid if the instrument is remote-
controlled. With transparent info fields the grid and traces underneath are still visible.
Dialog Transparency varies the transparency of all dialogs on a scale between 0% and 100%. 0%
transparency means that dialogs completely hide the diagram area in the background. With a
maximum transparency of 100%, the dialogs are still visible but clearly show the underlying traces
and display elements.
Keep Measurement Data for >Repeat Previous Cal< causes the raw measurement data of the
standards to be stored after the calibration is completed. This function is equivalent to the
parameter in the Measured Standards dialog of the calibration wizard (see detailed description
there) but applies to all calibrations.
No of Sliding Match Positions defines the maximum number of different positions to be measured
if a sliding match standard (sliding load) is used for calibration. The different positions appear in
the Measure Standards dialog of the calibration wizard. A sliding match calibration is valid after
three calibration sweeps at different match positions; however, calibration sweeps at additional
positions can still improve the accuracy. In general 4 to 6 positions are recommended.
Unit of Length selects the physical unit for lengths/distances,e.g. for distance-to-fault
measurements. The selected unit (metric units/m or feet) is also used as a default length unit for
remote control; see e.g. CALCulate<Chn>:TRANsform:DTFault:CENTer.
• Presets
The tab specifies whether a Preset affects the Active Setup or all open setups (Instrument). A
preset does not change any of the properties listed in the Resets tab of the System Configuration
dialog.
In the Preset Configuration panel, it is possible to specify whether the Preset command will
perform a factory preset or restore the settings stored to a user preset file. A user preset file is an
arbitrary setup (.zvx) file, to be stored using the Nwa File – Save Network Analysis... command. If
the current user preset file is not found (e.g. because it was deleted or moved), the analyzer
performs a factory preset.
In remote control, a user-defined preset must be initiated using the commands in the
SYSTem:PRESet:USER... subsystem. *RST and SYSTem:PRESet always restore the
factory preset settings.
• Resets
Provides several buttons to reset global instrument settings and properties. Global settings (e.g.
the data related to global resources) are not affected by an instrument Preset.
Use Default Directories also resets the custom header for trace files.
• Remote Settings
Specifies the Remote Language for the analyzer.
• The DEFAULT language corresponds to the instrument control commands reported in this
help system; see SCPI Command Lists.
• PNA, HP8510, HP8720, HP8753 denote command sets for network analyzers from other
manufacturers.
The ID String and the OPT String of the analyzer are adjusted to the selected Remote Language.
The strings can be queried via *IDN? and *OPT?, respectively.
• If the DEFAULT language is activated, the factory ID string Rohde&Schwarz,ZVL<Max.
Freq.-Ports>Port,<Serial_no>,<FW_Version> (e.g. Rohde&Schwarz,ZVL6-
2Port,1145101010100001,1.70.5) is set. The bit order for transferred binary data is
