and real-time eye diagram analysis
Jitter measurement has become a popular debugging technique.
However, traditional jitter analysis options are often costly and
focused on characterizations that may not be suited for real-time
debugging. The 6000 X-Series DSOX6JITTER option focuses on
real-time debugging for your everyday jitter analysis. Start your
analysis with the dedicated jitter button.
–– The integrated oscilloscope feature ensures the best real-
time user debugging experience, unlike a separate software
package
–– Flexible clock recovery, supporting
–– Constant frequency
–– First-order PLL (loop bandwidth)
–– Second-order PLL (loop bandwidth and damping factor)
–– Explicit clock
–– Flexible jitter measurements
–– Data TIE
–– Clock TIE
–– N-period
–– Period-period
–– + width to + width
–– - width to - width
–– + duty cycle
–– Flexible jitter and jitter component graphical representations
–– Jitter measurement histogram
–– Displays the distribution of the jitter
–– Jitter measurement trend
–– Graphically represents the jitter value time-correlated to
the input clock data signal under test
–– Smoothing can be applied
–– Jitter spectrum
–– FFT analysis of the jitter trend to determine the frequency
component of the jitter

Figure 19 is an example of a data TIE (time interval error) analysis
on a 1-Gbp PRBS (pseudo-random bit sequence) signal. The
data TIE measured 50-ps rms TIE jitter. The jitter trend and trend
smoothing plot quickly revealed the injected jitter to be square
periodic jitter. The jitter spectrum plot and frequency peak search
found the main jitter component to be near 500 kHz, contributing
42 ps. The event table also listed higher harmonic components
and their jitter contribution values. Finally, the histogram shape
showed a clear bimodal distribution indicating the presence of
deterministic jitter.
