Input and Output Ports
Input and Output Ports - Concepts
The pattern generator's input ports are used to set the pattern generator's clock
frequency and to manipulate the output signal with respect to jitter, error insertion
and signal output.
The pattern generator's output ports are used to supply a clock signal and trigger
for another device (for example, for the Serial BERT's error detector), and an
arbitrary data signal for testing your device.
Understanding the Pattern Generator's Input Ports
The pattern generator provides the following input ports:
• 10 MHz Ref In
This connector allows you to connect a 10 MHz reference clock. The Serial
BERT has a 10 MHz Ref In and Out port at the rear (two BNC connectors).
• Clock In
Allows you to connect a clock signal from another device.
• Error Add
Allows you to connect a device that generates a trigger for inserting a single
bit error in the output stream. In addition, it also allows you to control the
electrical idle state of Data Out and/or Aux Data Out.
