IGURE A-10: WIRE TYPE PROPERTIES WINDOW
Once a wire type has been defined, a wire can added to the system. This is done by selecting Add
Wire from the Add menu to bring up the Add new wire prompt. From here, select the wire type
that will be used for the new wire and enter a name for the wire. Once this information has been
provided, click on the Add button to add the wire to the system. When a wire is selected in the
System Explorer, the user can define whether the wire is connected to a source, which will prevent
its connection to other sources.

Passive Devices
In addition to the active system components, various passive components can be added to an
EX7000 system as well. For the purposes of this applet, a “passive device” is one that is not
connected to a drive line and, therefore, cannot be controlled by software. To add a passive device,
select Add Passive Device from the Add menu, select the desired passive device from the drop
menu when the Add New Passive Device prompt appear, enter a name for the device, then press
the Add button. The passive device will now be added to the System Explorer. When selected, a
detail pane appears with detail appropriate for that device. Wires can be selected from the wire
drop menus to establish the required connectivity.
SYSTEM CONFIGURATION EXAMPLE
As an example, a 2 x 2 RF matrix will be created as shown in Figure A-12 using one RDB, four
7202-20 SPDT switch modules, an Agilent 84904 attenuator, and a user-defined parallel port. In
Figure A-12, blue lines indicate wires in the system (such as W1), while red lines indicate drive
line allocations (such as K1_1). To begin, open the System Configurator, then click on New in the
File menu. When the RDB Count prompt appears, ensure that a “1” is entered in the text box
(note, this is the default value). Click on the OK button to begin configuration.
