Hardware-Generated PRBS - Procedures
The recommended way to load the data patterns to the pattern
generator and error detector is to use the
Pattern Select Form
dialog box.
See
“Loading Patterns to the Pattern Generator and Error Detector” on
Hardware-Generated PRBS - Reference
Use the
Pattern Select
dialog box to select the pattern(s) you want to write
to the pattern generator and the error detector. See
User-Defined Sequences
User-Defined Sequences - Concepts
This section describes the basics of user-defined sequences.
A sequence is created and maintained by means of the
Sequence Editor
that can be enabled from the Pattern window.
A sequence consists of up to four blocks. Each block can generate a
pause signal (constant 0 or 1), a divided clock signal, a 2^n -1 PRBS, or
a user pattern.
Single or multiple blocks can be looped. An overall loop restarts the
sequence after it has come to its end.
When to Use a Sequence
You may wish to test a device that uses a certain protocol for processing
data.
For example, the device might expect synchronization data, a preamble,
payload data, and a suffix.
All this can be provided by a user-defined sequence.
