Table 6: Jitter
Display (Option EYE and PHY)
Characteristic Performance requirement Reference information
Type Displays nume
rical and graphical readouts
of peak-to-peak jitter. Jitter derived from
demodulated recovered clock as described
in SMPTE RP19
2 2003. If Opt. PHY is
installed, then Jitter Waveform can also be
displayed
High-Pass Filter Settings Can be set to 10 Hz, 1 kHz, 10 kHz, or
100 kHz.
High pass filter has type-3 response for low
frequency rejection of 60 dB/decade below
the filter s
etting. High pass filter also applies
to digital readout, jitter waveform and Eye
diagram display, but not the reference clock
output. Th
ere are two independent Jitter
demodulators which may be configured with
different loop bandwidths. One is applied to
the upper
two tiles of the display, and the
other applies to the lower two tiles
