Setting up the Pattern Generator
Setting up the Pattern Generator - Concepts
The Serial BERT's pattern generator generates an output signal based
on a data pattern. It has the following possibilities for generating an
output signal:
•
Providing a wide range of clock frequencies
You can use the pattern generator's internal clock or an external
clock for defining the frequency of the outgoing stream.
•
Distorting the signal by adding jitter
You can connect an external delay control device (for example a
function generator) to add jitter to the generated signal.
•
Adding errors to the output stream
The Serial BERT can be set up to insert errors into the outgoing
stream either internally, according to an external signal, or manually
(from the operator).
•
Run-time switching between two patterns
You can set up two patterns and switch between them during
runtime either automatically, according to an external signal, or
manually.
•
Suppressing the output stream
The output signal can be suppressed according to an external signal.
The pattern generator also provides output ports that let you connect
an external instrument, such as an oscilloscope.
