Input Ports
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.
The pattern generator has the following inputs and outputs:
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.
•
