User guide

• Every sequence can be stored in a file and recalled from that file. However, the
SequenceExpression does not include user patterns. Recalling a sequence from
its file may fail if the referenced user patterns are not available.
A recalled sequence is not automatically downloaded to the pattern generator.
• In sequence mode, the function "Error Dector Pattern tracks the Pattern
Generator Pattern" is automatically disabled. You have to download the
expected (payload) pattern to the error detector.
• During initialization of the sequence, pure zeros are sent.
User-Defined Sequences - Procedures
You can create a new sequence, save it in a file, or load a saved sequence from its
file.
Creating a New Sequence
If you wish to create a new sequence:
1
Click the Sequence Editor. menu item from the Pattern submenu.
By default, the Sequence Editor shows one block that is automatically repeated.
It has a length of 512 bits and generates Pause0 data (pure zeros).
2
Click the Properties icon.
In the Properties window, set:
– the sequence start condition
– the number of blocks contained in the sequence (1 to 4)
3
Click Ok to close the Properties window.
4
Specify the data to be generated during execution of a block.
– Click the Edit button of the block.
– Choose from the list. For example, you can select a PRBS polynomial or
browse for a pattern file. A "None" block is completely ignored.
– If necessary, change the block length. The block length of user patterns is
derived from the file. Remember that such patterns are automatically
repeated until a multiple of 512 bits is reached.
