Creating Test Patterns
The PeRT
3
Phoenix System includes a library of predefined test patterns, that for many
users may fully satisfy their requirements.
Some users may wish to create additional test patterns or to modify the patterns supplied
with the system. A simple example of the need to create a test pattern is when the user’s
device has a vendor‐specific command which is required to place the device into a test
loopback mode. In this case, the vendor‐specific command can be created using the
Pattern Editor and then selected in the DUT Initialization panel of the Main tab in the
System Control Ribbon (see
“DUT Initialization” on page 50 ).
Creating a New Test Pattern
A new test pattern can be created by clicking on the Test Patterns tab in the Main Library
window, then clicking the Create New Item icon in the task bar.
When a new test pattern is created, it has certain default characteristics which are
determined by the Default Settings which are currently set for the system. To change the
Default Settings, click the Options tab on the System Control Ribbon and select the
desired values in the Default Settings panel.If the default settings are not desired, they
can easily be changed by, for example, selecting a different protocol in the Decode As field
of the Display Mode panel of the Pattern tab.
It is important to have the Decode As field set to the correct protocol for the pattern you
are defining. Not only does this dictate how the pattern is displayed in the pattern editor,
it also controls how it is sorted and displayed in the pattern picker. When the Create New
Item icon is clicked, a Pattern Editor window displays within the PeRT

window below the System Control Ribbon. The Pattern Editor window has two sections:
the upper section displays the actual data pattern being created, and the lower section
displays the current data decoded as a protocol primitive or frame using the protocol
selected in the Decode As field.
