CONFIGURATION MANAGEMENT - Global Attributes
The concept of Global Attributes is used for advanced configuration control and is unlikely to be used in simpler
setups. It is recommended that the user leave this tab empty until he has become familiar with other elements of
the configuration.
Global Attributes are used as a method of distinguishing equivalent Antenna Paths leading to the same
end-point or combination of end-points, which would otherwise be grouped together into a single Alternative
Group.
Global Attributes are tags, marked by capital letters A, B, C, etc., assigned to individual R-ports, in the
RF boxes->Rules tab of the respective RF box. Multiple attributes can be assigned to a single R-port, simply by
listing all of them in the
Global attributes
column for the given R-port.
When a path is being constructed, Global Attributes entered for R-ports along this path are concatenated, and
the resulting combination of attributes enters the matching process against the list in the Global Attributes tab.
For each line of that list, first, those attributes from the path's combination are selected, which are contained in
the list in
Group
column. Then, the resulting combination is matched against the combinations listed in the
Value list
column. If there is a match, this path is marked by the name from the
Name
column. If the
RX only
checkbox for that line is checked, the matching paths are marked as RX only.
For example, if a path passes through R-ports some of which have assigned Global Attributes AE and others B,
the resulting attribute list for this path is ABE. If then in the Global Attributes tab a line contains ABCD in the
Group column, this path's attribute combination for this line is AB, and this combination is searched for in the
Value list column of this line. If found, this path is marked by the name of this line and if RX only checkbox for
this line is checked, this path becomes also RX only. Otherwise, this line is ignored for this path.
This process is repeated for the rest of the list, and as a result, a path can have several markers at once; if there
was no match for the given path, it may have no marker at all. The Alternative Groups are then split so that only
paths with the same combination of markers are grouped together.
Configuring the Global Attributes tab
Like other tabs in Configuration Management, lines in this tab can be added/removed using the Add/Remove
button, and can be reordered using the Up/Down button. The order of lines has no significance.
Name
Every line in this tab must be given a name, which then serves as a marker if a match for a given path is found
according to the process described above. Highlight the line, and after a brief pause single-click on the name to
change it.
Group
This is the list of attributes which are taken into account when seeking a match for a path's attribute combination.
Highlight the line, and after a brief pause single-click to enter the group. Type simply all attributes (capital letters)
to be taken into account, e.g. “ABCD”.
Value list
After selecting only those attributes from the path's list which match the attributes in Group column, the resulting
combination is matched against a list of attributes' combinations in the Value list column. Highlight the line, and
after a brief pause single-click on the Value list to change it. Combinations in the list are separated by comma.
For example, the following string may be entered as a value list: “A,AB,AC,ABC”.
