Question:  I need higher frequency sinusoidal jitter (SJ) for my stressed eye testing. How do I get it with a BERTScope?
Answer:  The BERTScope models equipped with stress generation have the ability to generate SJ up to around 100 MHz; however they also have a sinusoidal generator for higher frequencies, intended for generating sinusoidal interference (SI) for standards such as 10GbE. If not being used to generate SI, the signal can be routed using a coax cable from the rear panel ‘SI Output’ connector, around to the front panel ‘HF Jitter’ input. This enables the generation of SJ from 100 to 1,000 MHz, easily controllable from the user interface.
