Max Pj Threshold. Sets the threshold level to determine periodic jitter by using
the C/N value averaged by the Median filter (the yellow trace in the lower view)
as the reference. A signal whose C/N value [dBc/Hz] is larger than the threshold
is regarded as a periodic jitter. The maximum periodic jitter in the analysis range
is shown in the measurement results (see Figure 3--75).
Setting range: 1 to 50 dB (default: 10 dB)
