Jitter/Amplitude Analysis Mode

Jitter Mode is an optional feature that, if installed, adds powerful jitter (time

and frequency domain) measurement capability to the Infiniium DCA.

Refer to

"Optional Features and Licenses" on page 2-16

for information on adding this

option. Jitter Mode can be extended to the amplitude domain by installing the

additional Option 300 software.

Refer to "Option 300, Advanced Amplitude

Analysis/RIN/Q-factor" on page

2-19.

Jitter Mode measures Total Jitter (TJ) as well as Jitter components such as

Periodic Jitter (PJ), Deterministic Jitter (DJ), and Data-Dependent Jitter

(DDJ). Measurement results are presented in graphs as well as tabular data.

While in Jitter Mode, you can view a representative eye diagram from which

the jitter measurements are derived. You can also temporarily switch to Eye/

Mask Mode in order to view the individual bit trajectories in the data pattern.

The 86100C uses a pattern trigger in Jitter Mode. But, because Jitter Mode

internally generates the pattern trigger and automatically detects bit rate, pat-

tern length, and trigger divide ratio, in most cases, you don't need to know or

to enter these values. Jitter Mode requires measurement data in the NRZ cod-

ing format. Measurements can not be performed on data using RZ coding.

Consult the 86100C Help for more information and procedures on using Jitter

Mode.
