Click Jitter Decomposition to enter the jitter decomposition configuration menu.
A. Set the pattern mode between Auto and
Manual. In the Manual mode, the pattern
length in bits, which represents the repetition
period of the data sequence, can be set as
user input. In the Auto mode, the pattern
length is automatically detected
B. Pattern length. When Pattern Mode = Auto,
this area is read-only. The pattern length is a
necessary parameter to calculate DCD and
DDJ
C. Enable/Disable the Bathtub plot. The "bottom"
of the bathtub expresses the degree of the
eye opening under the target bit error rate.
The result of jitter decomposition will be shown in the measured area. Users can add the jitter
components interested, including measurement values, histogram, track, and spectrogram.
29.5 Jitter Measure
Click the Jitter Measure in the Jitter analysis menu to recall the jitter measurement settings. The
operation method of adding jitter measurement parameters is the same as that of the measure closed
jitter function. Refer to the “Measurement” for details.
Statistics for each measurement item are automatically enabled when the measurement is activated.
Following are the descriptions of some jitter parameters.
