Making Measurements

Measuring Jitter Transfer

HOW TO:

View the Results

1

Choose the results FORMAT.
If

is chosen, a plot of the jitter transfer results against the

ITU-T mask is displayed.
If

is chosen, the results from which the graph is constructed are

displayed: Point number, Frequency, Mask amplitude (dB), Jitter Gain
(dB), Result.
If applicable, results 13 through 55 can be viewed on pages 2 through
5.

2

If

is chosen, choose the SCALE required.

provides a vertical axis range of +5 to -60 dB and is

recommended for viewing the high frequency portion of the graph.
This allows a clearer view of the difference between the actual result
and the ITU-T pass mask.

provides a vertical axis range of +3 to -3 dB and is

recommended for viewing the low frequency portion of the graph. This
allows a clearer view of the difference between the actual result and
the ITU-T pass mask.
