If P1 is used as input, sinusoidal interference is (or can be) added after the signal
has passed the chosen trace. Seen from the DUT, this is called "near end" injection.
If P2 is used as input, sinusoidal interference is (or can be) added at the beginning
of the trace. This is called "far end" injection.
Jitter Setup
Jitter Setup - Concepts
The Jitter Setup function is used for composing the total jitter in a defined and
calibrated way.
This function reflects the present setup of the Serial BERT's internal jitter
generation hardware (see also “Jitter Generation Block Diagram” on page 401).
The Jitter Setup display is divided into the following four sections:
• Jitter on/off button and delay line status area
• Jitter configuration area
• Jitter setup area
• Jitter switch area
Jitter On/Off Button and Delay Line Status Area
The Jitter On/Off button allows you to globally enable or disable the jitter
generation.
