3.1.1 Global Resources
The analyzer provides global settings that are mostly hardware-related and can be
used for all measurements, irrespective of the current measurement session or setup.
The settings are stored in independent files and do not enter into any of the setup files.
The following settings correspond to global resources:
E
Calibration kits
E
Connector types
E
Cal pool data including system error correction and power correction data
E
Color schemes
The data related to global resources are not affected by a
Preset
of the analyzer.
However, it is possible to delete or reset global resource data using the
Resets
tab in
the
System Config
dialog.
3.1.1.1 Setups
A setup comprises a set of
diagram areas
with all displayed information that can be
stored to a NWA setup file (*.nwa) and reused. Each setup is displayed in an
independent window. The setup file contains the following information:
E
General settings related to the setup
E
The trace settings for all traces in the diagram areas
E
The channel settings for all channels associated to the traces
E
The display settings for each diagram area
The
Nwa-File
menu is used to organize setups.
Demo 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 *.nwa
file for later use.
3.1.2 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.
E
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.
E
A channel contains hardware-related settings to specify how the network analyzer
collects data.
