settings are stored in independent files and do not enter into any of the setup files. The
following settings correspond to global resources:
●
Calibration kits
●
Connector types
●
Cal pool data including system error correction and power correction data
●
Color schemes
The data related to global resources are not affected by a "Preset" of the analyzer. How-
ever, it is possible to delete or reset global resource data using the "Resets" tab in the
"System Config" dialog.
3.1.2 Setups
A setup comprises a set of diagram areas with all displayed information that can be stored
to a NWA setup file (*.zvx) and reused. Each setup is displayed in an independent win-
dow. The setup file contains the following information:
●
General settings related to the setup
●
The trace settings for all traces in the diagram areas
●
The channel settings for all channels associated to the traces
●
The display settings for each diagram area
The "File" menu is used to organize setups.
In the "System – External Tools" submenu, you can find demo setups
*.vbs
for various
measurement scenarios. You can modify the demo setups and store them to a
*.zvx
file for later use. Moreover the "S-Parameter Wizard" provides predefined, optimized
setup s for many measurements.
3.1.3 Traces, Channels and Diagram Areas
The analyzer arranges, displays or stores the measured data in traces which are
assigned to channels and displayed in diagram areas. To understand the menu structure
of the instrument and quickly find the appropriate settings, it is important to understand
the exact meaning of the three terms.
●
A trace is a set of data points that can be displayed together in a diagram area. The
trace settings specify the mathematical operations used in order to obtain traces from
the measured or stored data and to display them.
●
A channel contains hardware-related settings to specify how the network analyzer
collects data.
●
A diagram area is a rectangular portion of the screen used to display traces. Diagram
areas belonging to the same setup are arranged in a common window. The settings
for diagram areas are described in
chapter 3.2.2, "Display Elements in the Diagram
A diagram area can contain a practically unlimited number of traces, assigned to different
channels. Diagram areas and channels are completely independent from each other.
