IGURE A-14: ADDING A 7202-20 RELAY AS “SW1”
Next, a wire type will be defined followed by the creation of wire connections to relays. To define
a wire type, select Add wire type from the Add menu. In this example, the wire type will be
called “Fifty_Ohm”. After entering the name, the Add button is clicked and the prompt is closed.
When selected in the System Explorer, the impedance and bandwidth of the wire appears. In the
example, the bandwidth has been changed to 20 GHz to match the bandwidth of the relay.

IGURE A-15: WIRE TYPE DETAIL PANE
Once a wire type has been defined, define the wires in the system. This done by selecting Add
wire from the Add menu. When the Add new wire prompt appears, the wire designators are
entered into the Name text field, one at a time, and then the Add button is clicked to add the wire
to the System Explorer.

IGURE A-16: ADDING A NEW WIRE AS “W1”
With the wires defined, switch connectivity can now be set. To set the pin connections for relay
SW1, select SW1 in the relay folder. Next, change the Pin (1) setting to “W1” to match the
connectivity in Figure A-12 by using the wire drop menu. Then change Pin (2) to “W3” and
Pin (C) to IN1 using the same method. Once all of the relays have been configured, their detail
panes should appear as in Figure A-17.
