Pspice Tutorial
The wiring in Pspice, sometimes, give students the headache. It
is a good practice
to use off-page connection in the circuit schematic. This
special wiring helps to
modular design by separating many block of circuits in different
. This tutorial will
walk you through the way to apply off-page connectors with a
focus on the usage in
the connection dependent sources.
Firstly, make sure you have CAPSYM.olb library come with your
Orcad installation.
Check the /orcad/Capture/libray folder to see if there is a
library named capsym.
If there is no such a library with that name, please copy the
file capsym.olb to that
folder.
It will bring you to the menu below from which you can add the
library capsym.olb
to use the off-page connector.

Choose capsym library from the list to bring you to the
following window
If your setup is properly done after you choose the off-page
connector, it will bringyou to the window below

Now, it is ready to perform an example of off-page connection
using the circuit
below
In this circuit, we have two independent voltage sources and one
dependent
voltage source. In practice, it is convenient to use off-page
connector for both of
type of sources. However, in this case we use the off-page
connector for the
dependent source only.
Remember to name the node that you want to use off-page
connector in every
connection with the same name. Such as input and ouput node in
our example.After you have complete your connection, you have to
double click the H
component and modify the gaincolumn to 50 as required by the
circuit.
