Programmable patterns
For special pattern requirements, pro-
grammable patterns up to 8 Mb in length
can be easily created with powerful editing
tools built into the N4980A multi-instru-
ment BERT software. Patterns can then
be uploaded into the N4960A serial BERT
controller.
The programmable pattern editor is used
to create and manage pattern streams.
Pattern streams are composed of one
or more sub-patterns. Each sub-pattern
contains a single pattern definition. Using
sub-patterns allows users to break down
complex patterns for easier organization.
Sub-patterns can be edited at the bit level

using the edit pattern dialog box. In this
dialog box, users can create, view, edit,
and find specific bit sequences.
Once the pattern definition is complete,
it can be validated and uploaded to the
N4960A serial BERT controller. It can also
be saved to the PC as a *.cpf file.
